Future Value = Present Value (1+r)n
a)
Future Value = $120000*(1+0.05)^4
Future Value = $145,860.75
b)
Interest = Amount Received at the end - Principal
Interest = $145,860.75-$120,000
Interest = $25,860.75
c)
Simple Interest = $120000*0.05*4
Simple Interest = $24,000
d)
Interest on Interest = $25,860.75-$24,000 = $1,860.75
