Answer:
Step-by-step explanation:
Let the number of visits to a pool = n
Charges of n visits = Number of visits × Charges per visit
= n × $4
= 4n
Let the membership amount of the pool = $m
So the inequality showing that a membership is less expensive than paying each visit to the pool will be
4n > m
Now we divide the inequality by 4
n >
Therefore, membership of the pool will be less expensive until number of visits to the pool is one fourth of the membership.
