Question

A caterer estimates that 2 gallons of fruit punch will serve five people.

How much additional punch is necessary to serve 75 people?

Need all the explanations

Answer 1

the answer is 28

Explanation:

This is simple

if 5 people need 2 gallons we can use that to figure out how many gallons 75 people need.

75 divided by 5 is 15. so if 5 fits into 75 15 times that means that 75 people need 15 times 2 gallons or 30 gallons of fruit punch.

But the problem ask how much "additional" fruit punch so we subtract 2 from 30 to get 28 additional gallons of fruit punch
