Create a program to store weekly expenses and revenues over a period of time. The program should
store the expenses and revenues in two global array variables. Values stored in the array at index k
represent the total revenues/expenses recorded during the k(th) week. Assume that the maximum number of weeks tracked is 250.
Add the following functions to your program:
-
A function that finds the total of all expenses incurred since week t for a given t.
-
A function that records the total expenses and revenues for the next unrecorded week. It must check if there is still space in the array.
-
A function that prints the number of weeks recorded
-
A function that prints all revenues and expenses recorded
-
A function that returns a pointer to the largest revenue recorded
Organize the program so the function prototypes are presented
first, and the definitions after the main
function. Your program should keep asking the user to select
one of the following options and execute
the corresponding function based on the user choice:
(A)
computed the total of all expenses,
(B)
add a new expense/revenue ,
(C)
print the number of weeks recorded,
(D)
print all revenues and expenses recorded,
(E)
print the largest revenue recorded, or
(F)
exit the program.

2) Suppose a lake is publicly owned, i.e. a common property resource, with free fishing for all. The number of fish caught varies with the number of people fishing as follows:
Labour Total Product
1 13
2 25
3 36
4 46
5 55
6 63
7 70
8 76
9 81
Assume the market price of these fish is $10 per fish, and this price is not affected by the number of fish caught in this lake. Assume that all fishermen can earn $100 per day in their next best alternative. Assume the fishermen share equally in the proceeds of the lake.
a) Explain much fishing will occur ina common property setting i.e. how many people would join the fishery?
b) Assume now that the lake is privately owned and the owner hires fishermen for $100 per day. How much fishing would the owner allow i.e. how many people would join the fishery?
c) Why is the common property result considered to be inefficient?

Brandlin Company of Anaheim, California, purchases materials from a foreign supplier on December 1, 2017, with payment of 31,000 korunas to be made on March 1, 2018. The materials are consumed immediately and recognized as cost of goods sold at the date of purchase. On December 1, 2017, Brandlin enters into a forward contract to purchase 31,000 korunas on March 1, 2018. Relevant exchange rates for the koruna on various dates are as follows:
| Date | Spot Rate | Forward Rate (to March 1, 2018) |
||||
| December 1, 2017 | $ | 4.90 | $ | 4.975 | ||
| December 31, 2017 | 5.00 | 5.100 | ||||
| March 1, 2018 | 5.15 | N/A | ||||
Brandlin’s incremental borrowing rate is 12 percent. The present value factor for two months at an annual interest rate of 12 percent (1 percent per month) is 0.9803. Brandlin must close its books and prepare financial statements at December 31.
