-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 an equation that can be used to determine the labor cost, C(x), of a repair that takes x hours.
A) C(x) = 30 + 23x B) C(x) = 30 - 23x C) C(x) = ( 30 + 23) x D) C(x) = 23 + 30x
