I need help with this one math problem.

Question

Two savings accounts pay interest rates that differ by 1%. Equal amounts of money were invested in each account for a year. One account returns $200 in interest and the other returns $225. What is the higher interest rate?

A. 7%

B. 8%

C. 9%

D. 10%

Answer 1

The answer would be 9%

You can find the investment amount using the differences of the investment then dividing by 1%

X*1%=25

X= 2500

You can then use this to find the intrest amount.

2500*x=225

X= .09 or 9%
