A movie rental website charges $7.00 per month for a membership and $3.50 per movie rental. If this month's bill is $42, how many movies did you rent?

Step-by-step explanation:

Hi. First off, welcome to , i see this is your first question. Hope I make a good first impression!. As for your problem:

You're going to want to set it up like this:

3.5x+7=42.

You're looking for the number of movies rented, which will be your variable

Subtract 7 from both sides

3.5x=35

and divide by 3.5 on both sides

x=10

So you rented 10 movies for the month

the answer is 5636.7
