Question

A delivery truck is transporting boxes of two sizes: large and small. The large boxes weigh 50 pounds each, and the small boxes weigh 35 pounds each. There are 115 boxes in all. If the truck is carrying a total of 4775 pounds in boxes, how many of each type of box is it carrying?

Answer 1

Answer:

y=65; x=50

Step-by-step explanation:

x+y=115

50x+35y=4775

y=115-x

50x+35(115-x)=4775

50x+4025-35x=4775

15x=750

x=50

50(50)+35y=4775

2500+35y=4775

35y=2275

y=65
