A base for an airport runway, 100 m wide, 2000 m long and 500 mm thick, is to be constructed out of a clayey sand excavated from a nearby borrow pit, where the in situ water content is 6%. This soil is being transported in trucks having a capacity of 8 m 3 , where each load weighs 13200 kg. In the subbase course, the soil will be placed at a water content of 14.2% to a dry density of 1890 kg/m 3 . (1000 litres = 1m3 ) (a) How many truck loads will be required to complete the job? (7 points) (b) How many litres of water should be added to each truck load? (7 points) (c) If the base becomes saturated later, without any change in volume, what would be the water content? Assume Gs = 2.7.

On January 1, 2000, Audrey Corporation issued $100,000 of 10% coupon rate bonds to yield an effective rate of 12%. Interest is paid semiannually on June 30 and December 31. The bonds mature in five years, i.e., on January 1, 2005. Audrey incurred $10,000 in issuance costs and has a September 30^th fiscal year end.

Required:

1. Prepare the journal entry to record the bond issuance.

2. Prepare the amortization schedule for the entire bond’s life (5 years).

3. Prepare the journal entries that Audrey Corporation would make on:

1. December 31, 2000.

2. June 30, 2001.

3. September 30, 2001.

4. Prepare Audrey’s Statement of Cash Flows for the fiscal year ended September 30, 2001.

5. Assume that on September 30, 2001 Audrey calls the bonds for 97. Prepare the journal entry to record the bond call.

6. Prepare Audrey’s Statement of Cash Flows for the fiscal year ended September 30, 2001 assuming the call took place.

An interchange ramp is being designed to reach its high point after climbing for 2000 feet with a grade of +6%.Use the Deceleration/acceleration curves to answer the following:

A.What is the critical length of grade for this ramp based on the 10 mph speed reduction definition?

B.What would be the speed of a fully loaded truck at the top of the ramp if it enters the ramp at 60 mph?

C.If the ramp descends from its high point for a distance of 1000ft at a rate of -1%, what would the speed of the truck in part B be at the bottom?

In a perfectly competitive market, a profit-maximizing firm produces 2000 pounds of butter per week in the long run equilibrium. Answer each of the following questions with two diagrams, one for the butter market and another for the individual butter firm. If the market demand for butter increases …

a) How does it affect the butter market and the individual butter firm in the short run?

b) In the long run, how does the butter market adjust, and what will be the impacts on the individual butter firm?        

Steelcase Inc. has a robotic welder that cost $89,500. Shipping and site preparation cost $2000 and installation cost $700. At the end of the 4 th year of service, this robotic welder was traded in for a new robotic welder with a purchase price of $95,900, shipping and site preparation cost $2,300 and installation cost $800. The trade- in allowance for the old robotic welder was $32,000 for purchasing the new robotic welder.This equipment is a 7-year MACRS class.

a)What is the cost basis of the new robotic welder for computing the amount of depreciation for income tax purposes?

b)If instead of trading in the old robotic welder, Steelcase Inc. sold the old robotic welder on the open market for $32,000, then:

i) What is the cost basis of the newrobotic welder?

ii) For the sold old robotic welder, will Steelcase Inc. need to pay a gains tax or get a tax benefit and calculate the value (assume 21% tax rate).

Consider a supplier order allocation problem under multiple sourcing,
where it is required to buy 2000 units of a certain product from
three different suppliers. The fixed set-up cost (independent of the
order quantity), variable cost (unit price), and the maximum capacity
of each supplier are given in Table 5.15 (two suppliers offer quantity
discounts).
The objective is to minimize the total cost of purchasing (fixed plus
variable cost). Formulate this as a linear integer programming problem.
You must define all your variables clearly, write out the constraints to
be satisfied with a brief explanation of each and develop the objective
function.
TABLE 5.15
Supplier Data for Exercise 5.5
Supplier Fixed cost Capacity Unit Price
1 $100 600 units $10/unit for the first 300 units
$7/unit for the remaining 300 units
2 $500 800 units $2/unit for all 800 units
3 $300 1200 units $6/unit for the first 500 units
$4/unit for the remaining 700 units

A parachutist whose mass is 65 kg drops from a helicopter hovering 2000 m above the ground and falls toward the ground under the influence of gravity. Assume that the force due to air resistance is proportional to the velocity of the​ parachutist, with the proportionality constant b₁ = 20 ​N-sec/m when the chute is closed and b₂ = 90 ​N-sec/m when the chute is open. If the chute does not open until the velocity of the parachutist reaches 25 ​m/sec, after how many seconds will the parachutist reach the​ ground? Assume that the acceleration due to gravity is 9.81 m divided by sec squared.
The parachutist will reach the ground after
_______ seconds.
​(Round to two decimal places as​ needed.)
