Question

One serving of a cereal is 3/4 cup. Each box of cereal has about 9 cups of cereal and costs $3.80. Is the price per serving greater than $0.50? Complete the explanation.

Answer 1

The price per serving is $0.315, therefore, it's less than $0.5

Explanation:

In order to calculate the price per serving, we can first calculate the price per cup, this is done by dividing the total value of the box by the number of cups it can serve:

`price_(cup) = (3.8)/(9) = 0.42`

Since each serving is
`(3)/(4)` of a cup, then it's price has the same proportion and is given by:

`price_(serving) = (3)/(4)*0.42 = 0.315`

The price per serving is $0.315, therefore, it's less than $0.5
