735 at 7% for 2 1/2 years?
Assumed that interest is compounded half yearly.
Formula for total amount is
#A = P (1 + (r/n))^(nt) where
P = principal amount (the initial amount you borrow or deposit)
r = annual rate of interest (as a decimal)
t = number of years the amount is deposited or borrowed for.
A = amount of money accumulated after n years, including interest.
n = number of times the interest is compounded per year
Given : P = 735, r = 0.07, t = 5/2, n = 2
