Linda has $9000 to invest. She invested x dollars in an account that earned 3% simple interest and the remainder of the money in an account that earned 2.6% simple interest. In one year, both accounts together earned $250 interest. How much was invested in each account?

Answer 1

If x is at 3%, the remainder (9000-x) is at 2.6%. So, add up the interest:

.03x +.026(9000-x) = 250
