Answer:
Equation: 120 = 3x + 45
Solution: 25 movies
Step-by-step explanation:
First let's create an equation.
Let y = cost of membership and x = # of movies rented.
It cost $3.00 for each movie rented.
So the cost of # of movies rented can be represented by 3x.
There is also a one time fee of $45.
So the total cost of the membership can be represented by the equation y = 3x + 45.
Now that we have created an equation, we want to find how many movies can be rented if you spend $120.
We can find this by plugging in 120 into y and then solving for x
so we have y = 3x + 45
y ( or money spent ) = 120
120 = 3x + 45
now solve for x ( or movies rented )
subtract 45 from both sides
75 = 3x
divide both sides by 3
25 = x
So if $120 is spent you can rent 25 movies
