Mr. Drysdale earned $906.25 in interest in one year on money that he had deposited in his local bank. If the bank paid an interest rate of 6.25% APR, how much money did Mr. Drysdale deposit?

Interest rate: 6.25%; Total amount of interest $906.25.

Let x be the amount invested so that to get $906.25 as interest gain:
