Asked by Lily

Brody deposited $500 into an account that
earns 4.2% interest compounded annually. He
makes no additional deposits and no withdrawals.
Approximately how much interest will the account
have earned after 7 years?

A $167
B $420
C $542
D $665

I think the answer is D. But can someone tell me how to check my answer with work. I don't want to use a calculator.
Answered by Steve
you are going to need a calculator of some kind, unless you want to evaluate

500(1.042^7) - 500

by hand

By the way, D is the amount in the account, but it is not the answer to the question.

this is so dumb you always put wrong answers. Only put it if you are certain that it is right. People are copying you guys because they think you are right and they fail because of you guys putting wrong answers.
