Question

A package states that there are 60 calories in 12 crackers and 75 calories in 15 crackers. Since the relationship is proportional, how many calories are there in 180 crackers? x y 12 60 15 75

Answer 1

900

Explanation:

We can write the proportion as ...

calories/crackers = 60/12 = y/180

Multiplying by 180, we have ...

180(5) = y = 900

There are 900 calories in 180 crackers.
