<em><u>The inequality is:</u></em>

Membership of the pool will be less expensive until number of visits to the pool is one fourth of the membership amount
<em><u>Solution:</u></em>
Given that,
A pool charges $4 each visit or you can buy a membership
Let "n" be the number of times you visit the pool
Let the membership amount of the pool be "m"
A pool charges $4 each visit
Therefore, cost for "n" visit is: $ 4n
<em><u>The inequality showing that a membership is less expensive than paying each visit to the pool is:</u></em>
4n > m
Divide both sides by "4"

Therefore, membership of the pool will be less expensive until number of visits to the pool is one fourth of the membership amount
