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 75

 pounds. The truck is transporting 65

 large boxes and 60

 small boxes. If the truck is carrying a total of 4800

 pounds in boxes, how much does each type of box weigh?

Answer 1

You can solve that equation that way:

x + y= 75

65x+60y = 4800

x: Large boxes

y: Small boxes

x + y = 75

65x+60y = 4800

-60 (x + y)= 75 (multiplying by (-60)

65x+60y= 4800

-60x-60y= -4500 (Adding the two)

65x+60y= 4800

5x = 300

x= 60

Then we substitute x for its value in the equation x + y= 75

60 + y = 75

y= 15

So, the large boxes weigh 60 pounds, while the small ones weigh 15 pounds.

Answer 2

s is the weight of a small box

75 - s is the weight of a large box

60s + 65(75 - s) = 4800

Can you solve for s and answer?
