Roman will have to pay $89.67 for his school supplies. 
Since you needed help, I’ll show you my work so you know for next time:

A good way to solve these problems is to first figure out the system if the functions were regular equalities. Then, to determine which direction the inequality sign goes, ask whether the graph is shaded above or below y. For above, that means y is greater than... below, less than. A solid line means greater/less than or equal to.
