Solve the problem.The cost for labor associated with fixing a washing machine is computed as follows: There is a fixed charge of $25 for the repairman to come to the house, to which a charge of $20 per hour is added. Find an equation that can be used to determine the labor cost, C, of a repair that takes x hours. Write the final answer in the form C = mx + b.
A. C = -20x + 25 B. C = 45x C. C = 25x + 20 D. C = 20x + 25
