Picture Maker is a free-standing photo kiosk consumers use to download their digital photos and make prints. Shashi Sharma has a small business that leases several Picture Makers from the manufacturer for $120 per month per kiosk, and she places them in high-traffic retail locations. Customers pay $0.18 per print. (The kiosk only makes six- by eight-inch prints.) Sharma has one kiosk located in the Sanchez Drug Store, for which Sharma pays Sanchez $80 per month rent. Sharma checks each of her kiosks every few days, refilling the photographic paper and chemicals, and collects the money. Sharma hires a service company that cleans the machine, replaces any worn or defective parts, and resets the kiosk's settings to ensure the kiosk continues to provide high-quality prints. This maintenance is performed monthly and is independent of the number of prints made during the month. The average cost of the service runs about $90 per month, but it can vary depending on the extent of repairs and parts required to maintain the equipment.

Paper and chemicals are variable costs, and maintenance, equipment lease, and store rent are fixed costs. If the kiosk is malfunctioning and the print quality deteriorates, Sanchez refunds the customer's money and then gets his money back from Sharma when she comes by to check the paper and chemical supplies. These occasional refunds cause her variable costs per print for paper and chemicals to vary over time.

The following table reports the results from operating the kiosk at the Sanchez Drug Store last month. Budget variances are computed as the difference between actual and budgeted amounts. An unfavorable variance (U) exists when actual revenues fall short of budget or when actual expenses exceed the budget. Last month, the kiosk had a net loss of $23, which was $87 more than budgeted.

Finance - CFIN 6th Edition Chapter 14, Problem 12 Solution

I am not able to come up with the same solution posted in the Chegg Study Textbook solution for this question beginning with step 4 of 7. The issue has to do with computing the EAR. I followed the textbook solution, but the response does not make sense for the EAR. Please help.

Chapter 14 Problem 12

Montana Allied Products (MAP) must borrow $1.7 million to finance its working capital requirements. The bank has offered a 45-day simple interest loan with a quoted interest rate of 8 percent. Calculate the loan’s APR and assuming there is (a) no compensating balance requirement and (b) a 15 percent compensating balance requirement, which MAP must satisfy from the loan proceeds. (c) How much does MAP have to borrow so that it has $1.7 million to pay its bills if the loan requires a 15 percent compensating balance?

The formula and the solution provided does not match up

  1. A psychologist is interested in the relationship between intelligence and academic motivation. She recruits eight participants for a study. Each participant completes an intelligence test and a measure of academic motivation. Scores for the eight participants are in the table below.

4. (20 pts) GA Industries manufactures handling equipment used in distribution centers. One product, called a Liftmaster, has three components: a frame with strap, a motor and two supports. The most recent order has been for 4000 Liftmasters for next month. The sales and production departments must work together to determine delivery schedules. Although the processes used in the manufacture of the three components vary, there are three areas where the production manager is concerned about the availability of resources. These three areas, their usage by the three components, and their availability are detailed in the table.

The subcontractor requires that the minimum purchase of frame is 600. Due to their production capacity onstraint, the subcontractor can only supply up to 2500 motors.

Develop a linear programming model that would tell GA how to fill the order for 4000 Liftmasters at the minimum cost.

Using an Aging Schedule to Account for Bad Debts

Sparkle Jewels distributes fine stones. It sells on credit to retail jewelry stores and extends terms that require the stores to pay in 60 days. For accounts that are not overdue, Sparkle has found that there is a 90% probability of collection. For accounts up to one month past due, the likelihood of collection decreases to 75%. If accounts are between one and two months past due, the probability of collection is 60%, and if an account is over two months past due, Sparkle Jewels estimates only a 40% chance of collecting the receivable.

On December 31, 2016, the credit balance in Allowance for Doubtful Accounts is $11,500. The amounts of gross receivables by age on this date are as follows:

Category Amount
Current $195,000
Past due:
    Less than one month 44,300
    One to two months 24,800
    Over two months 1,400

Required:

1. Prepare a schedule to estimate the amount of uncollectible accounts at December 31, 2016.

Over two months 1,400
Totals $265,500

2. On the basis of the schedule in part (1), prepare the journal entry on December 31, 2016, to estimate bad debts. Indicate the effect on financial statement items by selecting "–" for decrease (or negative effect), "+" for increase (or positive effect) and "NE" for No Entry (or no effect) on the financial statement.

Answer the following questions:

Given a M x N matrix where each cell has a cost associated with it, find the minimum cost to reach last cell (0,0) of the matrix from its first cell (M,N). We can only move one unit right or one unit down from any cell. i.e. from cell (I,j), we can move to (i, j-1) or (i-1,j).

  1. Suppose that are also allowed to move diagonally to lower-right cell as well as downward and right. Find the minimum cost using pure recursion. (30 points)

Example output:

Minimum cost is 34.
