Question

A delivery truck is transporting boxes of two sizes: large and small. The large boxes weigh 50 pounds each, and the small boxes 25 weigh pounds each. There are 115 boxes in all. If the truck is carrying a total of 4125 pounds in boxes, how many of each type of box is it carrying?

Answer 1

number of small boxes = 65

number of large boxes = 50

Explanation:

Let the small boxes be represented by s

Let the large boxes be represented by b

b+s = 115 (if you add the number of small boxes and large boxes)

50b + 25s = 4125 (The cost of the boxes has to be 4125)

Solve the two equations simultaneously

s = 65

b = 50
