You rent a video game for $3.50 a month. your total cost of rentals for the month was $31.50. write and solve an equation to find the number of video rentals for the month

a video game costs $3.50 a month. You're total cost is $31.50

Let video games = x

You're equation is:

31.50 = 3.50x

Solve for x. Isolate the x. Note the equal sign. What you do to one side, you do to the other. Divide 3.50 from both sides

31.50/3.50 = 3.50x/3.50

x = 31.50/3.50

Divide

x = 9

9 is your answer

hope this helps
