Write a system of inequalities that describes the possible solutions to the problem.Matt is going to invest no more than $4000 into two accounts earning 2% and 4% simple interest. He would like the accounts to earn at least 
after one year. He wants to invest 
or less in the account earning 4% simple interest. Write a system of inequalities to describe this situation and solve by graphing.
