Question

Jane has $5000. She invests a portion of her money at a simpl
e interest rate of 5% and the rest
of her money at a simple interest rate of 6.2%. After one year,
the total interest earned on these
investments is $292.00. How much money did she invest at 5%?

Answer 1

x= dollars invested at 5%
5000-x= dollars invested at 6.2%
.05x = interest earned on x dollars
.062(5000-x)=interest earned on 5000-x dollars.
Add the interest earned on x dollars + interest earned on 5000-x dollars and set it equal to 292
