Question

Constance invested $4000 for 3 years in a savings account paying simple interest with a yearly interest rate of 3.5%. How much simple interest did she earn?

Answer 1

She made $420 profit. If you want to know how to do this then in your calculator put in $4000 times 103.5% and then you get 140. Then do 140 times 3 representing the 3 years and there.
