I don't understand why we have to divided by 2 (time). The question didn't mention much about timing. Anyone can help? Thank you very much!
American Coat company estimates that 60,000 special zipper will be used in the manufacture of men's jackets during the next year. Reese Zipper company has quoted a price of $0.6 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?
Choice “a” is correct.
Cost to purchase 60,000 zippers:
60,000 x 0.6 = 36,000
The opportunity cost is the forgone interest on the 33,000 cash payment (the first 3000 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:
Principle Rate Time Interest
33,000 x 0.08 x 1/2 = 1320July 22, 2011 at 8:13 pm #290635fdtParticipant
It's because the principle balance on which you would earn the interest would be decreasing incrementally with each monthly purchase. Since the monthly purchases are made in equal installments over the year, the interest earned would be the average principle balance during the year ($33,000 / 2 = $16,500) times the 8% annual interest rate. This comes to the $1320. The below schedule should help to illustrate it:
_ Principle Interest Rate Interest
Month Balance (8% / 12) Earned

Thanks for the explanation. What kind of situation that we don't need to divided by 2? I would like to make a comparison. Thank you!
