Mathematical ReasoningHong has a bag with 8 balls numbered 1 through 8. He is playing a game of chance.
This game is this: Hong chooses one ball from the bag at random. He wins $1 if the number 1 is selected, $2 if the number 2 is selected, $5 if the number 3 is selected, $6 if the number 4 is selected, $8 if the number 5 is selected, and $10 if the number 6 is selected. He loses $14 if 7 or 8 is selected.
(a) Find the expected value of playing the game.
(b) What can Hong expect in the long run, after playing the game many times?
(He replaces the ball in the bag each time.)
Hong can expect to gain money.
He can expect to win dollars per selection.
Hong can expect to lose money.
He can expect to lose dollars per selection.
Hong can expect to break even (neither gain nor lose money).

Mathematical ReasoningPeriodic Inventory by Three Methods
The units of an item available for sale during the year were as follows:
Jan. 1 Inventory 14 units at $35
Feb. 17 Purchase 12 units at $36
Jul. 21 Purchase 18 units at $37
Nov. 23 Purchase 15 units at $38
There are 14 units of the item in the physical inventory at December 31. The periodic inventory system is used. Round average unit cost to the nearest cent and final answers to the nearest whole dollar, if required.
a. Determine the inventory cost by the first-in, first-out method.
b. Determine the inventory cost by the last-in, first-out method.
c. Determine the inventory cost by the weighted average cost method.

Mathematical ReasoningMcCall Manufacturing has a WACC of 10%. The firm is considering two normal, equally risky, mutually exclusive, but not repeatable projects. The two projects have the same investment costs, but Project A has an IRR of 15%, while Project B has an IRR of 20%. Assuming the projects' NPV profiles cross in the upper right quadrant, which of the following statements is CORRECT?
a. Each project must have a negative NPV.
b. If the crossover rate is 8%, Project B will have the higher NPV.
c. Only one project has a positive NPV.
d. Since the projects are mutually exclusive, the firm should always select Project B.
e. If the crossover rate is 8%, Project A will have the higher NPV.

Mathematical ReasoningMulroney Corp. is considering two mutually exclusive projects. Both require an initial investment of $10,800 at t = 0. Project X has an expected life of 2 years with after-tax cash inflows of $6,600 and $7,400 at the end of Years 1 and 2, respectively. In addition, Project X can be repeated at the end of Year 2 with no changes in its cash flows. Project Y has an expected life of 4 years with after-tax cash inflows of $4,300 at the end of each of the next 4 years. Each project has a WACC of 8%. Using the replacement chain approach, what is the NPV of the most profitable project? Do not round the intermediate calculations and round the final answer to the nearest whole number.
a. $3,718
b. $3,339
c. $3,442
d. $2,960
e. $3,408
