Last year, Jim had

$10,000

to invest. He invested some of it in an account that paid

7%

simple interest per year, and he invested the rest in an account that paid

8%

simple interest per year. After one year, he received a total of

$770

in interest. How much did he invest in each account?

Note that the ALEKS graphing calculator can be used to make computations easier.
