Question

Andrea had $43.50 to spend on groceries. After buying 4 boxes of cereal, she had $27.70 left. If each box of cereal costs the same amount, what is the price of one box of cereal?

Answer 1

To determine the price of one box of cereal, we first need to find out how much money Andrea spent on the cereal.

Initially, Andrea had $43.50. After buying the cereal, she had $27.70 left. We can calculate the amount spent on the cereal as follows:

\[
\text{Amount spent on cereal} = \text{Initial amount} - \text{Amount left}
\]
\[
\text{Amount spent on cereal} = 43.50 - 27.70 = 15.80
\]

Next, we know that Andrea bought 4 boxes of cereal for a total of $15.80. To find the price of one box of cereal, we divide the total amount spent by the number of boxes:

\[
\text{Price of one box of cereal} = \frac{\text{Amount spent on cereal}}{\text{Number of boxes}} = \frac{15.80}{4}
\]

Calculating this gives:

\[
\text{Price of one box of cereal} = 3.95
\]

Therefore, the price of one box of cereal is

\[
\boxed{3.95}
\]
