Step-by-step explanation:
<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

<h2>
There are 120 pine trees and 180 maple trees.</h2>
Step-by-step explanation:
Total number of trees = 300
Given that for every two pine trees there will be 3 maple trees.
Let 2t be the total number of pine trees.
Then total number of maple trees is 3t.
Total number of trees = 2 t + 3 t = 5 t
That is
5t = 300
t = 60
Total number of pine trees = 2t = 2 x 60 = 120
Total number of maple trees = 3t = 3 x 60 = 180
There are 120 pine trees and 180 maple trees.
