Cost is $139.60

Step-by-step explanation:

From the question we can acquire that the charges of plumbing repair was $29.60 for 1 1/4 hour. The labor is $56 per hour during the job. However, for the service of plumbing at call charges are $40.

Putting all the given values in a formula in order to find the cost of repair,

Cost (C) = Charges of plumber + Hour to the power of labor charges + service call.

C = $ 29.60 + 1 ¼ ^ $56 + $ 40

C = $ 29.60 + 5/4 ^ $ 56 + $ 40

C = $ 29.60 + $ 70 + $40

C = $139.60

Therefore, the cost of the repair is $139.60
