Question

Diana invests $11,000 into two accounts. One account earns 9% interest and the other earns 15% interest. After one year her total interest earned from the two accounts totals $1,452. How much did Diana invest in the 15% account? Type in your numerical answer only; do not type the $ symbol or any words or letters with your answer.

Answer 1

1.15X + 1.09(11000 - X) = 11000 + 1452

1.15X + 11990 - 1.09X = 12452

0.06X = 462

X = 7700
