Question

Livvi invests $19,430 in a savings account at her local bank which pays 1.8% simple annual interest. She also deposits $16,470 in an online savings account which pays 2.7% simple annual interest. After six years, which account will yield more interest, and approximately how much more interest will it yield? a. The online account will give $2,668 more interest. b. The online account will give $570 more interest. c. The local account will give $2,960 more interest. d. The local account will give $2,390 more interest.

Answer 1

At $19,430 savings with 1.8% annually, the amount yields to $21,528.44 after six years. On the other hand, the deposits of $16,470 at 2.7% simple annual interest creates only $19,138.14. This means that the 2nd strategy works better than the first one. The situation where simple interest occurs naturally is when the principal doesn't change over time. This is true with an interest-only mortgage, for example, where your monthly payments only pay the interest on your loan, but don't pay down the loan itself.

Answer 2

I=prt
I interest earned
P principle
R interest rate
T time 6 years

For the first the interest earned is
I=19,430×0.018×6
I=2,098.44

For the second the interest earned is
I=16,470×0.027×6
I=2,668.14 yield more


how much more interest will it yield
2,668.14−2,098.44=569.7=570

So the answer is b
Hope it helps:-)
