If you invest $8,600 at a 3.95% simple annual interest rate, approximately how long will it take for you to have a total of $21,000? a. 25 years b. 36 years c. 45 years d. 60 years

Well, Doing 8,600 x .0395, you get 339.7, then if you do that x 25, that's too low if you add 8600 to it, 36 years if you do 339.7 x 25, then add 8600 its extremely close to 21000. And since you put approximately, since this will round up, the best answer choice is definitely B

Hope this helps. Have a great day!
