A box of cereal states that there are 75 calories in a three fourths 3/4-cup serving. What is the unit rate for calories per cup? How many calories are there in 2 cups of the cereal?

a) The unit rate for calories per cup is 100 calories per cup

b) 200 calories in 2 cups of cereal.

Step-by-step explanation:

A box of cereal states that there are 75 calories in a three fourths 3/4-cup serving.

a) What is the unit rate for calories per cup?

This is calculated as:

3/4 cup = 75 calories

1 cup = x

Cross Multiply

3/4x = 75 calories × 1

x = 75 calories /3/4 cup

x = 75 ÷ 3/4

x = 75 × 4/3

x = 100 calories per cup

The unit rate for calories per cup is 100 calories per cup

b) How many calories are there in 2 cups of the cereal?

From the above question

3/4 cup = 75 calories

2 cups = x

Cross Multiply

3/4x = 75× 2

x = 150 ÷ 3/4

x = 150 × 4/3

x = 200 calories

There are 200 calories in 2 cups of cereal.

correct answer is b. 27/8
