months that increase dramatically and rise to a peak at Christmas.

However, during the summer and fall, the store must

build up its inventory to have enough stock for the Christmas

season. In order to purchase and build up its stock during the

months when its revenues are low, the store borrows money.

Following is the store’s projected revenue and liabilities

schedule for July through December (where revenues

are received and bills are paid at the first of each month).

>month Month	Revenues	Liabilities
July	>$20 $20,000	$60,000
August	30,000	>60 60,000
September	40,000	>80 80,000
>october October	50,000	30,000
November	>80 80,000	30,000
December	100,000	20,000

At the beginning of July the store can take out a sixmonth

loan that carries an 11% interest rate and must be

paid back at the end of December. (The store cannot reduce

its interest payment by paying back the loan early.)

The store can also borrow money monthly at a rate of 5%

interest per month. Money borrowed on a monthly basis

must be paid back at the beginning of the next month.

The store wants to borrow enough money to meet its cash

flow needs while minimizing its cost of borrowing.

this problem.

the store could secure a 9% interest rate for a 6-month

 

loan from another bank?
