Answer 1

Plumber B at a cheap price of $215

Explanation:

Plumber A charges $25 for a house call and $50 for each hour that is spent on the job

Plumber B charges $35 for a house call and $45 for each hour that is spent on the job

It will take 4 hours to complete the job

Plumber A

= $25 + 4×50

= $25 + 200

= $225

Plumber B

= $35 + 4(45)

= $35 + 180

= $215

Hence I would use plumber B because it will cost me a cheaper price of $215
