Solve the problem.The cost for labor associated with fixing a washing machine is computed as follows: There is a fixed charge of $35 for the repairman to come to the house, to which a charge of $26 per hour is added. Find an equation that can be used to determine the labor cost, C, of a repair that takes x hours.
A. C = 35 - 26x B. C = 35 + 26x C. C = (35 + 26)x D. C = 26 + 35x
