Answer 1

Answer:

p≥8

Explanation:

The cost of a pound of candy = $7

The cost of p pounds of candy = $7p

Trey will spend at least $56 on candy. This means he can spend exactly or greater than $56.

The inequality representing this problem is:

$7p\ge56$

To solve the inequality for p, divide both sides by 7.

$\begin{gathered} \frac{7p}{7}\ge\frac{56}{7} \\ p\ge8 \end{gathered}$

Trey can buy 8 or more pounds of candy.
