Question

Trey buys candy that costs $7 per pound. He will spend at least $56 on candy. What are the possible numbers of pounds he will buy?Use p for the number of pounds Trey will buyWrite your answer as an inequality solved for p.

Answer 1

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} (7p)/(7)\ge(56)/(7) \\ p\ge8 \end{gathered}`

Trey can buy 8 or more pounds of candy.
