CHAPTER 15(13.)

On January 1, 2018, Nath-Langstrom Services, Inc., a computer software training firm, leased several computers under a two-year operating lease agreement from ComputerWorld Leasing, which routinely finances equipment for other firms at an annual interest rate of 4%. The contract calls for four rent payments of $15,500 each, payable semiannually on June 30 and December 31 each year. The computers were acquired by ComputerWorld at a cost of $101,000 and were expected to have a useful life of Five years with no residual value. Both firms record amortization and depreciation semi-annually. (FV of $1, PV of $1, FVA of $1, PVA of $1, FVAD of $1 and PVAD of $1) (Use appropriate factor(s) from the tables provided.)

Required:
Prepare the appropriate entries for both the lessee and the lessor from the beginning of the lease through the end of 2018. (If no entry is required for a transaction/event, select "No journal entry required" in the first account field. Round your intermediate calculations to the nearest whole dollar amount.)

• Record the lease revenue received by ComputerWorld Leasing.
• Record the Depreciation expense for ComputerWorld Leasing.
• Record the lease revenue received by ComputerWorld Leasing.
• Record the Depreciation expense for ComputerWorld Leasing.

An ice cube of mass 11.4 g and initial temperature -6.0°C is held in your hand such that the water resulting from the melted ice reaches the temperature of your hand, 36.2°C. In order to accomplish this, how much heat (in kJ) must be absorbed by the ice cube and resulting water? Assume that all the water remains in your hand. Hint: Tables 14.1 and 14.2 in your textbook will be useful here.

Detail design a gear reducer that would meet (at a minimum) the following design specification:

• Power to be delivered: 40 hp
• Input speed: 1750 rpm
• Output speed: 40–44 rev/min
• Usually low shock levels, occasional moderate shock
• Input and output shafts extend 4 in outside gearbox
• Maximum gearbox size: 18-in x 18-in base, 36-in height
• Output shaft and input shaft in-line
• Connection to a roller and conveyor via a chain drive

Other than the reducer design, design the intermediate and main shafts, including complete specification of the gears, bearings, keys, retaining rings, and shaft.

Homework 4

Put all home works together and use methods to simplify code. Also expand to have preferences and budget for wall coverings the way that was done for floor options

Use separate Methods to calculate the change for each the Door, Window and Bookcase (Hint – you may want to use 2 methods for the book case effects since one is floor and other is wall).

The user shall input the dimensions of the room and the eventual output will be how the walls and flooring is done and how much budget is left.

The user will input the number of doors, windows, and bookcases and the dimensions of each which will be used to adjust the total wall and floor space needed to be covered. The system will output the square feet of wall and floor after adjustments.

The user will be asked for his budget for the walls and if he has a preference for the type of material for the wall. The system will accept as input the costs for the different wall coverings and determine which wall covering the user can afford – being either his preference or the most expensive if he does not have a preference. It’s also possible the user can not afford any wall coverings. The budget left after the wall covering is kept for how much money is left.

The system will output the initial budget for walls, the selected option and cost and what is left in the budget for walls.

The same process will work for floor coverings with the same output for flooring.

YOU also have COST OPTIONS FOR WALLS, A USER PREFERENCE AND A BUDGET, YOU WILL DO THE SAME FOR THE WALL. SAME RULES APPLY – IF 0 THEN JUST PICK MOST EXPENSIVE, IF PREFERENCE GIVE PREFERENCE IF CAN AFFORD, IF NOT GIVE WHAT CAN AFFORD.

There are four options for wall cover (Ceramic Tile = 1; Paneling = 2, Wallpaper = 3; and paint = 4) each with a cost per square foot The program will ask for input and read in the budget in dollars and cents, the cost per square foot for each of the different wall options and also ask for which one the customer prefers where 0 means the customer does not care and 1-4 if they have a specific preference.

Output the users preference, their budget, if they got their preference, and what they did get. Also how much budget is left.

You will be graded on how well you map this to methods and how good the comments are explaining what the program does.

Use the following for data (it is the same as HW 3 so you should get the same selection answers for flooring as you get there.

For Flooring use:

Tile= $4.00 /sq ft; Wood = $3.00/ sq ft; Carpet = $2.00/ sq ft and linoleum = $1.00/sq ft).

Use the following as the budget and preference:

There are four options for wall cover (Ceramic Tile = 1; Paneling = 2, Wallpaper = 3; and paint = 4) each with a cost per square foot

For all three test renovation projects use Tile= $4.00 /sq ft; Paneling = $3.00/ sq ft; Wallpaper = $2.00/ sq ft and paint = $1.00/sq ft).

Use the following as the budget and preference:

Cassi Cronin is the Women’s head varsity hockey coach at USGB University. She has enjoyed considerable success over the years and is considering starting a summer hockey camp. USGB University would charge Coach for rooms, meals and ice-rink time for participants, plus a 10% commission based upon the price charged to campers. Coach Cassi has heard of the CVP experts in Acct 2220 and is asking for your help (and she is willing to pay!). You state that some of the important factors in analyzing such an opportunity involve setting fees, predicting enrollments and estimating the behavior of costs. Accordingly, planning ahead involves estimates and assumptions. Coach has provided estimates as follows:

Coach Cassi states that other camps have typically employed one assistant coach for each 15 campers, excluding the director (Cassi in this case). One problem is that you need to hire the coaches before you know the enrollments, although it is usually possible to find one or two at the last minute. It is, however, important to hire most of the assistant coaches early so you can use their names in the marketing brochures. Further, while the enrollment and prices given are averages, variations exist, with enrollments generally ranging from 60 to 110 and weekly camper fees ranging from $160 to $330. As might be expected, the better-known camps have higher enrollments at higher prices, but they also pay more for more well-known coaches. Coach Cassi will keep any profits (or suffer any losses), so she wants to be fairly confident before proceeding with this venture.

Required: Use the CVP Equation Method (& template) to Analyze:

1. If Coach hires the needed number of assistant coaches, incurs the commission and realizes all of the averages above, what would be her weekly pre-tax profit? To determine this, identify whether each cost is variable or fixed and setup a CM Template (as shown in class) to confirm all data relationships. Next use the equation method (i.e. S – VC – FC = “something”) to notate your analysis. Third, return to the CM template and confirm your work and “prove” your answer.

2. Assuming Coach hires the required number of coaches to support her planned enrollments, what would be her break-even point in the number of campers and in sales dollars?   Again, use the equation approach to develop (notate) an equation to address this question. Once determined, prepare a new CM template to prove your answer.

3. Assuming Coach hires the required number of coaches to support her planned enrollments, what weekly per-camper fee would enable coach to earn an after-tax weekly profit of $2,400 assuming the expected number of campers is realized? Assume a 40% income tax rate. Hint: Make sure to consider how you will “notate” the commission (which will be a function of weekly fee charged). In other words, keep the commission separate from the other variable costs as you prepare your equation. When completed, return to your CM Template to confirm your answer.

4. List two qualitative (i.e. subjective) considerations that, in your opinion, may affect this decision. In essence, what else should Coach consider before committing to this venture?  

5. Marketing Dept Question: Based upon your answer in PART C, what camper fee would you recommend Coach Cassi actually charge (and include in her marketing brochures)? Why?

6. As consultant, what would you charge (invoice) Coach for your analysis and professional services?
