Question

A box of cereal states that there are 72 calories in a 3 fourth cup serving what is the unit rate for calories per cup? HHow many calories are there in 4 cups? The unit rate is _ calories per cup

Answer 1

4 cups = 384 calories ; 1 cup = 96 calories

Explanation:

Given that:

3/4 cups = 72 calories

Let Number of calories in 4 cups = x

3/4 = 72

4 = x

Cross multiply

(3/4)x = 72 * 4

(3/4)x = 288

Multiply both sides by 4/3

(3/4 * 4/3)x = 288 * 4/3

x = (288 * 4) /3

x = 384

Hence, 4 cups has 384 calories

Number of calories per cup :

4 cups = 384 calories

1 cup = 384 / 4

1 cup = 96 calories
