question 179

Short Answer

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 $22 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) = (35 + 22) x
B) C(x) = 35 - 22x
C) C(x) = 22 + 35x
D) C(x) = 35 + 22x

• A) C(x) = (35 + 22) x
• B) C(x) = 35 - 22x
• C) C(x) = 22 + 35x
• D) C(x) = 35 + 22x
