Question

A convenience store supplies two types of protein bars. One protein bar has 320 calories in the 2-ounce size. How many calories are in the 3-ounce size of the bar?

Answer 1

There are 480 calories in a 3 ounce bar

Answer 2

Since one protein bar has 320 calories in a 2-ounce size, we can divide 320 by 2. When solving, we get 160. This means there are 160 calories in one protein bar.

We are trying to find how much calories are in the 3-ounce size, so we must multiply 160 by 3.

The final answer to your question is 480. There are 480 calories in the 3-ounce protein bar.
