Adelivery truck is transporting boxes of two size: the combined weight of a large box and a small box is 65 pounds. the truck is transporting 60 large boxes and 55 small boxes if the truck is carrying a total of 3775 pounds in boxes, how much does each type of box weigh?

pretty much about the same as before.

a = weight of a large box

b = weight of a small box.

we know their combined weight is 65 lbs, thus a + b = 65.

we also know that the truck has 60 large ones, and 55 small ones, thus 60*a is the total weight for the large ones and 55*b is the total weight for the small ones, and we know that is a total of 3775, 60a + 55b = 3775.

gdp is the best phrase!
