Answer:

The school much purchase 40 items.

Step-by-step explanation:

Food truck A equation: y = 1.5x + 50

Food truck B equation: y = 2.75x

In order to find our answer, we can set the two equations equal to each other:

1.5x + 50 = 2.75x

1.5x - 1.5x + 50 = 2.75x - 1.5x

50 = 1.25x

50/1.25 = 2.25x/1.25

x = 40
