An exterminator charges $80 to visit a home and $35 to spray each room. If the total

bill was $395, how many rooms were sprayed? Write an algebraic equation that

represents this situation. Then solve it.

Your variable is r for the number of rooms

So your equation is 395= 35*r + 80

First subtract 80 from both sides of the equation

315 = 35r

Next divide 35 from both sides of the equation

And your final answer is 9 rooms in total he sprayed.

Total cost = 35(#ofrooms) + 80
