A person invests $7,500 part at 5% and the remainder at 4% simple interest. If the total interest at the end of the first year was $346.50, find the amount invested at 4%.

total interest=346.5=7500*.05 + x*.04

solve for x.

ooopsss, I misread the problem. The total amount invested was 7500..

total interest=346.5=(7500-x)*.05 + x*.04

solve for x.
