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 $23 per hour is added. Find a linear equation that can be used to determine the labor cost, y, of a repair that takes x hours.
A. y = 23 + 30x B. y = 23x - 30 C. y = 30 + 23x D. y = 30 - 23x
