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 less than 
in the account earning 4% simple interest. Write a system of inequalities to describe this situation and solve by graphing.
A. x - y ? 4000 0.02x + 0.04y ? 80 x ? 0 y ? 0 B. x + y ? 4000 0.02x + 0.04y ? 80 x ? 0 y ? 1000 C. x + y ? 80 0.02x + 0.04y ? 4000 x > 0 y ? 0 D. 0.02x + 0.04y - 80 ? 4000 x ? 0 y ? 0
