Question

Anthony deposits $800 into a savings account that carns 3.5% interest annually.

Answer 1

Explanation:

800 x 1,035ⁿ

Answer 2

after 1 year he will get : 800 + 800 x 3,5% = 800 x 1,035 = $828

after 2 years he will get : 828 x 1,035 = 800 x 1,035 x 1,035 = 800 x 1,035²

so

after n years he will get : 800 x 1,035ⁿ
