How many of each type of box is it carrying?

Number of large boxes: 55

Number of small boxes:65

Step-by-step explanation:

Let be "l" the number of large boxes and "s" the number of small boxes.

Set up a system of equations:

Use the methof of elimination. Mulitply the first equation by -60 and add both equations. Then solve for "s":

Substitute s=65 into any of the original equations and solve for "l":

Number of large boxes = 55

Number of small boxes = 65

Step-by-step explanation:

We know that large boxes weight 60 pounds each while small boxes weight 30 pounds each and they are 120 boxes in total which weigh 5250 pounds in total.

Assuming to the number of large boxes and to be the number of small boxes, we can write the following equations:

--- (1)

--- (2)

From equation (1):

Substituting this value of in (2):

s = 65

Now finding the value of :

l = 55

Therefore, number of large boxes = 55 and number of small boxes = 65.
