Question

A can of 3 tennis balls sells for $2. If Sal spent more than $24 on tennis balls, which inequality can be used to find n, the number of tennis balls Sal could have bought?

Answer 1

A is your answer.

Answer 2

The inequality that can be used to find the number of balls he bought is:
`(2)/(3)*n > 24`

Solving the inequality gives us:
`n > 36`. He bought more than 36 balls.

Explanation:

In order to solve this problem we first need to find the cost of each ball, because the number of balls he bought, n, multiplied by the cost of each ball must be more than $ 24. If a can with 3 tennis balls costs $ 2, then the cost of each ball is given by the division of the total cost of the can by the number of balls. We have:

`ball = (2)/(3)`

Each ball costs
`\$(2)/(3)`, then the inequality that can be used to find the number of balls he bought must be:

`(2)/(3)*n > 24`

Solving for "n", gives us:

`n > 24*(3)/(2)\\n >36`
