An investment adviser invested $14,000 in two accounts. One investment earned 4% annual simple interest, and the other investment earned 2.5% annual simple interest. The amount of interest earned for 1 year was $458. How much was invested in each account?

Answer 1

Invested $X @ 4%.
Invested $(14,000-X) @ 2.5%.

0.04X + 0.025(14000-X) = $458.
Solve for X.
