Answer 1

Diane received an $80 gift card.

The coffee costs $8.04 per pound.

After buying, she had $47.84 left.

Based on the given information, we can form the following equation

`80-8.04x=47.84`

Where x refers to the pounds of coffee she bought. Let's solve for x

`\begin{gathered} 80-47.84=8.04x \\ x=(32.16)/(8.04) \\ x=4 \end{gathered}`

Hence, she bought 4 pounds of coffee.
