Question

Maia received a $70 gift card for a coffee store. She used it in buying some coffee that cost $7.97 per pound. After buying the coffee, she had $30.15 left on her card. How many pounds of coffee did she buy?

Answer 1

If Maia had a $70 gift card and had $30.15 left after buying coffee then:

$70 - $30.15= $39.85 cost of the coffee she bought.

$\begin{gathered} \frac{39.85}{7.97}=\text{ 5 pounds of coffee. } \\ \end{gathered}$

Therefore, Maia bought 5 pounds of coffee at
