A rental moving truck can haul a maximum of 7,500 pounds. Dejuan has boxes that weigh 40 pounds and boxes that weigh 75 pounds. How many of each kind of box can he haul in one load?

If x represents the number of 40-pound boxes and y represents the number of 75-pound boxes, which graph correctly shows the solution to the problem 40x + 75y ≤ 7500?

X, Y graph. X range is negative 300 to 300, and y range is negative 300 to 300. Dashed line on graph has negative slope and runs through 0, 100 and 187.5, 0. Below line is shaded.
