Last year, Salma had $$30,000$ to invest. She invested some of it in an account that paid $5\%$ simple interest per year, and she invested the rest in an account that paid $10\%$ simple interest per year. After one year, she received a total of $$2600$ in interest. How much did she invest in each account?

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