60. Terese deposited $6 000 into a bank account that pay 2% every year
How much will she earn if for the first 4 years:
=> First Year 6 000 x 0.02
=> 120
=> 6 000 + 120 = 6 120
=> Second Year the money is 6 120
=> 6 120 * .02 = 122.4
=> 6 120 + 122.4
=> 6 242.4
=> For the third year the money is 6 242.4
=> 6 242.4 x 0.02 = 124.848
=> 6 242.4 + 124.848
=> 6 367.248
=> And for the 4th year
=> 6 367.248 * .02 = 127.34
=> 6 494.6
So his money will be 6 494.6 dollars.
