you want to get a membership at a video store. the membership is $45 plus $3.00 for each movie you rent. How many movies can you rent if you spent a total of $120 ( i really need the equation and solution)

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
