A delivery truck is transporting boxes of two sizes: large and small. The combined weight of a large box and a small box is 55 p
ounds. The truck is transporting 60 large boxes and 50 small boxes. If the truck is carrying a total of 3150 pounds in boxes, how much does each type of box weigh?
1 answer:
Answer:
Large boxes = 40 lbs.
Small boxes = 15 lbs.
Step-by-step explanation:
L = Large Box
S = Small Box
I started by making the equations, L + S = 55 and 60L + 50S = 3150. I made the first equation L = 55 - S and substituted that in for L in 60L + 50S =3150. After finding S, I plugged that back into L + S = 55 and got the answers.
