Item 14 possible points: 5 the total cost of repairing a car is the sum of the amount paid for parts and the amount paid for labor. you paid $132 for parts and $65 for each hour of labor. the total cost to repair the car was $229.50. how many hours did it take to repair the car? which equation best models this problem? let x = number of hours worked 229.5 – 65 = 132x 132x + 65 = 229.5 132 + 65x = 229.5 132 + 65 = 229.50x

Lets work out the problem from the beginning. Let  be the number of hours worked. We know that you paid $65 for each hour, and remember that the numbers of hours worked is , so you paid for those hours . We also know that you paid $132 for parts, a total cost of $229.5, so:
parts + worked hours = total cost 

And now that we have our equation from the model, lets solve for  to find how many hours took to the repair the car:





We can conclude that it took 1 and a half hour to repair the car.
