Question 75174: The cost for labor associated with fixing a washing machine is computed as follows: There is a fixed charge of $20 for the repairman to come to the house, to which a charge of $22 per hour is added. Find an equation that can be used to determine the labor cost, C(x), of a repair that takes x hours.

C(x)=22x + 20
The 22x is the $22 per hour and the x is the number of hours. The $20 charge to actually come to the house is the final 20 which as added on to the charge for actual working time.
