A small company plans to spend $10,000 in year 2 and $10,000 in year 5. At an interest rate of effective 10% per year, compounded semiannually, the equation that represents the equivalent annual worth in years 1 through 5 is:

(a) A = 10,000(P∕F10%,2)(A∕P,10%,5) + 10,000(A∕F,10%,5)

(b) A = 10,000(A∕P,10%,4) + 10,000 (A∕F,10%,5)

(c) A = 10,000(P∕F,5%,2)(A∕P,5%,10) + 10,000 (A∕F,5%,10)

(d) A = [10,000(F∕P,10%,5) + 10,000] (A∕F,10%,5)
