Question

A gym is selling monthly memberships for $30 each and reusable water bottles for $6 each. The gym needs to make $900 by the end of the month. Use the graph to approximate the number of water bottles that the gym must sell if it sells 24 gym memberships.

A. If the gym sells 24 memberships, it must sell 5 water bottles.
B. If the gym sells 24 memberships, it must sell 15 water bottles.
C. If the gym sells 24 memberships, it must sell 20 water bottles.
D. If the gym sells 24 memberships, it must sell 25 water bottles.

Answer 1

The gym must sell 30 water bottles along with 24 gym memberships to reach the target of $900, as the revenue from 24 memberships totaling $720, leaving $180 to be covered by selling water bottles at $6 each.

Step-by-step explanation:

To determine the number of water bottles the gym must sell if it sells 24 gym memberships to make $900, we can set up an equation based on the given prices. Each gym membership is $30, and each water bottle is $6. If the gym sells 24 memberships, the revenue from the memberships is 24 × $30 = $720. The gym needs an additional $900 - $720 = $180 to meet the $900 goal. To find out how many water bottles are needed to make the remaining $180, we divide $180 by the cost per water bottle, which is $6.

$180 ÷ $6 = 30 water bottles

Therefore, if the gym sells 24 memberships, it must sell 30 water bottles to make a total of $900.
