Question

A fruit company delivers its fruit in two types of boxes: large and small. A delivery of 3 large boxes and 5 small boxes has a total weight of 135 kilograms. A delivery of 9 large boxes and 7 small boxes has a total weight of 279kilograms. How much does each type of box weigh?

Answer 1

Answer:

You can not tell unless you have information about the relationship between the small and large boxes (for example, a large box is 2 times the weight of a small box) You can only tell that a small box and a large box's weight together is 34.5 kilograms.

Step-by-step explanation:

3L + 5S = 135

9L + 7S = 279

12L + 12S = 135 + 279

12(S+L) = 414

S+L = 34.5
