To calculate the amount of money that Jim will have on the deposit in 7 years, we will have to calculate the future value of the deposited amount
Future Value(FV) = PV*(1+r)^n
PV = 12,000
r = 6% = 0.06
n = 7 years = 7
FV = 12000*(1+0.06)^7
FV = 12000*1.06^7
FV = 18,043.56
a. How much will jim have on deposit at the end of seven years - $18,043.56
