Linear Equation

Question

A delivery truck is transporting boxes of two sizes: large and small. The combined weight of a large box and a small box is 55pounds. The truck is transporting 50 large boxes and 55 small boxes. If the truck is carrying a total of 2825 pounds in boxes, how much does each type of box weigh?

Answer 1

Set the large box weight as x, then the weight of small box should be 55-x

Then we should know 50x+55(55-x)=2825

50x+3025-55x=2825

solve for x=40 which means the weight of big box is 40, the weight of small box is 15.
