Question

A truck that can carry no more than 7700 lb is being used to transport refrigerators and upright pianos. Each refrigerator weighs 200 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 19 refrigerators and 9 pianos overload the​ truck? Explain.

Answer 1

200R + 475P = 7700

200(19) + 475(9) = 7700

3,800 + 4,275 = 7700

8075 = 7700 IS NOT EQUAL So Yes It Will Overload The Truck.
