Abe plans to use $21,000 to open a savings account with an annual interest rate of 6%. How much more interest will he earn over 4 years if he chooses a compound interest account, with interest compounded annually, instead of a simple interest account?
interest compounded annually: A = P (1 + r)t
simple interest: I = P • r • t

Answer 1

P = 21,000
r = 0.06
t = 4

Plug it into both formulas and tell me what you get when you plug it into the compound interest formula and the simple interest formula :)
