Answer:
The number of movies must be greater than 10
Step-by-step explanation:
Let
x ----> the number of movies
y ----> the total cost
we know that
The linear equation in slope intercept form is equal to
where
m is the slope or unit rate
b is the y-intercept or initial value
In this problem we have
<em>Membership</em>
The slope is equal to
The y-intercept is equal to
---> enrollment fee
so
The linear equation is
----> equation A
<em>Non-Members</em>
The slope is equal to
The y-intercept is equal to
---> Is a proportional relationship
so
The linear equation is
----> equation B
Solve the inequality
Divide both sides by -3
Remember that when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol
so
therefore
The number of movies must be greater than 10
