Why do they multiply it by 1/2 for the time?
American Coat Company estimates that 60,000 special zippers will be used in the manufacture of men’s jackets during the next year. Reese Zipper Company has quoted a price of $.60 per zipper. American would prefer to purchase 5,000 units per month, but Reese is unable to guarantee this delivery schedule. In order to ensure availability of these zippers, American is considering the purchase of all 60,000 units at the beginning of the year. Assuming American can invest cash at eight percent, the company’s opportunity cost of purchasing the 60,000 units at the beginning of the year is?
a.
$1,440
b.
$2,640
c.
$1,320
d.
$1,500
Explanation
Choice “c” is correct.
Cost to purchase 60,000 zippers:
60,000 × .60 = $36,000
The opportunity cost is the forgone interest on the $33,000 cash payment (the first $3,000 would have had to be paid in either case).
The $33,000 cash payment made evenly throughout the period is the same as making the total payment in the middle of the period. The solution is:
