A box of cereal states that there are 72 calories in a 3 4-cup serving. What is the unit rate for calories per cup? How many calories are there in 4 cups of the cereal?

96 calories per cup

384 calories in 4 cups

Step-by-step explanation:

In this scenario, we can use the rule of three to calculate the number of calories in a single cup like so...

72 calories   <==========>    or 0.75 cup

 x  calories   <==========>  1 cup

(1 * 72) / 0.75 = 96 calories

Now we see that there are a total of 96 calories per cup of cereal. In order to find the total amount of calories in 4 cups of cereal, we simply need to multiply the number of calories per cup by 4, like so...

96 * 4 = 384 calories

There are a total of 384 calories in 4 cups of cereal.

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27
