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? looking for the amount at 4% and also the amt. at 2.5%.

Answer 1

Let X = amount invested at 4%, then
(14,000-X) = amount invested at 2.5%.

The equation is
0.04X + 0.025(14,000-X) = 458.00
Solve for X and 14,000-X.
