Solve the problem.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 $23 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.
A. C(x) = 23 + 20x
B. C(x) = 20 + 23x
C. C(x) = 20 - 23x
D. C(x) = ( 20 + 23) x
