Question 1102514
i get selection C.


the formula to use is f = p * (1 + r) ^ n


f is the future value
p is the present value
r is the interest rate per time period #####
##### time period is in quarters therefore take the annual interest rate and divide it by 4 to get the quarterly interest rate (not the %).
n is the number of time periods #####
##### time period is in quarters therefore take the number of years and multiply them by 4 to get the number of quarters.


in your problem:


f = 11100
p = what you want to find
r = 7.9% / 100 = .079 / 4 = .01975
n = 20 * 4 = 80


formula becomes 11100 = p * (1.01975) ^ 80
solve for p to get p = 11100 / ((1.01975) ^  80)
your result is p = 2321.805628


that's selection C.
