Solve the problem.The cost for labor associated with fixing a washing machine is computed as follows: There is a fixed charge of $30 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(x), of a repair that takes x hours.
A. C(x) = 30 - 26x B. C(x) = 26 + 30x C. C(x) = 30 + 26x D. C(x) = ( 30 + 26) x
