Question

An actor invests money at 8%, and $34000 more than four times the amount at 9%. The total annual interest earned from the investment is $45300. How much did he invest at each amount?

Answer 1

a represents the amount at 8%

4a + 34000 represents the amount at 9%

 

0.08a + 0.09(4a + 34000) = 45300

 

Can you solve for a?
