Audrey invested 140 dollars. She earned a simple interest of 3% per year on the initial investment if no money was added or removed from the investment, how many years will it take to earn 8.40 in interest? Answers- A- 1 year. B- 2 years. C-3 years. D-4 years. Need help quickly this is due soon thank you!
since it's simple interest, you don't compound it. (thank god lol) 3% of $140 (this is for 1 year) is .03*140=4.2 if you double that, it would be $8.4, which means it took 2 years B would be correct
