​Beryl's Iced Tea currently rents a bottling machine for $ 53,000 per​ year, including all maintenance expenses. It is considering purchasing a machine instead and is comparing two​ options: a. Purchase the machine it is currently renting for $ 165,000. This machine will require $ 23,000 per year in ongoing maintenance expenses. b. Purchase a​ new, more advanced machine for $ 260,000. This machine will require $ 17,000 per year in ongoing maintenance expenses and will lower bottling costs by $ 13,000 per year.​ Also, $ 35,000 will be spent up front to train the new operators of the machine. Suppose the appropriate discount rate is 8 % per year and the machine is purchased today. Maintenance and bottling costs are paid at the end of each​ year, as is the cost of the rental machine. Assume also that the machines will be depreciated via the​ straight-line method over seven years and that they have a​ 10-year life with a negligible salvage value. The marginal corporate tax rate is 40 %. Should​ Beryl's Iced Tea continue to​ rent, purchase its current​ machine, or purchase the advanced​ machine? To make this​ decision, calculate the NPV of the FCF associated with each alternative.

A steady two-dimensional laminar fully-developed flow downward between

two fixed parallel plates inclined at 50" with horizontal is shown in figure. The

pressure gradient in the direction of the flow is -3935 N/m' per m. Note the

space between parallel plates is 5mm.Use the Navier-Stokes equation in the

flow direction to determine:

a-Velocity distribution of the flow between two plates.

b-Shear stress distribution of the low between two plates.

c- The average velocity of the flow

d- Maxinmum velocity

e-Mininmum shear stress.

f-The shear stress on the two plate

g-What will be the slope of the plate required to produce zero shear stress at the lower plate

17. An appliance store carries a specialty model of microwave ovens. The demand for the microwave oven is relatively constant at 2500 units per year. Placing an order costs the store $500 regardless the quantity ordered. Carrying one unit over a one year period costs the store $50. The store opens 300 days per year and the lead time for this item is 12 working days. Because of the special features of the microwave oven, customers may buy it whether it is currently available in the store. Hence, the store is considering selling it on a back order basis if it is beneficial. It is estimated that one unit on back order for a one year period costs the store $150.

Assuming shortage is allowed and the store manager is sure that shortages will not become lost sales, determine the annual holding cost.

1. An appliance store carries a specialty model of microwave ovens. The demand for the microwave oven is relatively constant at 2500 units per year. Placing an order costs the store $500 regardless the quantity ordered. Carrying one unit over a one year period costs the store $50. The store opens 300 days per year and the lead time for this item is 12 working days. Because of the special features of the microwave oven, customers may buy it whether it is currently available in the store. Hence, the store is considering selling it on a back order basis if it is beneficial. It is estimated that one unit on back order for a one year period costs the store $150.
   Assuming shortage is allowed and the store manager is sure that shortages will not become lost sales, determine the annual total relevant, including ordering, holding and shortage, cost.

Consider the game of craps designed by Econ 261 Hotel students. The game consists of rolling two fair six-sided dice. You win a dollar if the sum of the dots on the two dice is 2, 3, 4, or 5; if the sum of the dots on the two dice is 9, 10, 11, or 12 you lose a dollar. You win nothing, (that is you get $0) if the sum is 6, 7, or 8. The variance of X, Var(X) is:

Zen Inc. manufactures two types of products, the G1 and the T1 model airplane. The manufacturing process consists of two principal departments: production and assembly. The production department has 58 skilled workers, each of whom works 7 hours per day. The assembly department has 25 workers, who also work 7-hour shifts. On an average, to produce a G1 model, Zen Inc. requires 3.5 labor hours for production and 2 labor hours for assembly. The T1 model requires 4 labor hours for production and 1.5 labor hours in assembly. The company anticipates selling at least 1.5 times as many T1 models as G1 models. The company operates five days per week and makes a net profit of $130 on the G1 model, and $150 on the T1 model. Zen Inc. wants to determine how many of each model should be produced on a weekly basis to maximize net profit.

If the numbers of G1 and T1 products produced each week are denoted as G and T respectively, the function that describes Zen, Inc.’s sales prediction for a week is

Jiminy's Cricket Farm issued a 20-year, 7 percent semiannual coupon bond 5 years ago.The bond currently sells for 94 percent of its face value. The company's tax rate is 24 percent. The book value of the debt issue is $45 million. In addition, the company has a second debt issue, a zero coupon bond with 10 years left to maturity; the book value of this issue is $30 million, and the bond sells for 65 percent of par.

a. What is the company's total book value of debt?

b. What is the company's total market value of debt?

c. What is the aftertax cost of debt?

Use a 0.05 significance level to test the following claims:

Claim: the two populations have equal variances.

The test statistic is  
The larger critical value is  
The conclusion is
A. There is sufficient evidence to reject of the claim that the two populations have equal variances. (So, we can assume the variances are unequal.)
B. There is not sufficient evidence to reject the claim that the two populations have equal variances. (So, we can assume the variances are equal.)

Claim: the two populations have the same mean.

The test statistic is  
The positive critical value is  
The negative critical value is  
The conclusion is
A. There is not sufficient evidence to reject the claim that the two populations have the same mean.
B. There is sufficient evidence to reject the claim that the two populations have the same mean.
