An auto repair shop charges $85 per hour for labor to fix a car. The labor on your bill for a car repair is $212.50. Write an equation and solve it to determine how many hours you were charged for.
So the total is 212.50. The charge is 85 an hour. Hour will be represented by x. So one hour x is 1 and 1x85 is 85. x is 2 for two hours and 2x85 is 170 and so on.
So to put that together, the equation is:
212.50=85x
Divide 85 to both sides:
x=2.5
You were charged for 2.5 hours, or 2 hours and 30 minutes.
Hope this helped!
