A fruit company delivers its fruit in two types of boxes: large and small. A delivery of 7 large boxes and 9 small boxes has a total weight of 255 kilograms. A delivery of 5 large boxes and 3 small boxes has a total weight of 135 kilograms. How much does each type of box weigh?

Large box = 18.75 kg

Small box = 13.75 kg

Step-by-step explanation:

x = weight of large boxes

y = weight of small boxes

7x + 9y = 255

5x + 3y = 135

Solve the systems of equations:

(x, y) = (18.75, 13.75)
