A truck that can carry no more than 6700 lb is being used to transport refrigerators and upright pianos. Each refrigerator weigh
s 250 lb and each piano weighs 475 lb. Write and graph an inequality to show how many refrigerators and how many pianos the truck could carry. Will 12 refrigerators and 9 pianos overload the truck? Explain. Let x be the number of refrigerators in the truck and y be the number of pianos in the truck. Write an inequality to show how many refrigerators and how many pianos the truck could carry.
The inequality is [250x+475y] \leq [6700]. The answer to the question is yes the truck is overloaded because if you plug the in the inputs, 7275 is not less than or equal to 6700.
