Compost costs $10 per cubic yard and topsoil costs $2 per cubic yard. Maria needs more than 10 cubic yards of topsoil. She can spend no more than $50. The graph below represents the amount of each she can buy.

On a coordinate plane, 2 straight lines are shown. The x-axis shows cubic yards of compost, from 0 to 10, and the y-axis shows cubic yards of topsoil, from 0 to 16. A horizontal dashed line is at y = 10. Everything above the line is shaded. A solid straight line has a negative slope and goes through (3, 10) and (5, 0). Everything to the left of the line is shaded.
