Question 871312: I am trying to figure out this word problem:
Joyce invests $7500 in two savings accounts. One account earns interest at 4% per year; the other earns 2.5% per year. The total interest earned from both accounts after one year is $132.50. How much was originally deposited in each account?
This is what I have so far, but it does not correspond to the answer that the book gives:
.04x + .025(7500-x) = 132.50
.04x + 187.5 - .025x = 132.50
187.5 + .015x = 132.50
-187.5. -187.5
.015x = -55
X = -3666.67

Hi
.04x + .025(7500-x) = 132.50 Yes
.04x + 187.5 - .025x = 132.50 Correct Set UP
187.5 + .015x = 132.50 | 132.50 has to be a typo
-187.5. -187.5 Yes
.015x =
