3. Shelby and Shannon are both plumbers. Shelby charges $15 per hour
whilst Shannon charges $2 per pipe fixed. Shelby fixes 10 pipes per hour. A
hotel wants to hire a plumber to fix 40 pipes. Which plumber should the
hotel hire?
O A Shelby
O B. Shannon
C. Both
D. None

Answer 1

A. Shelby

Step-by-step explanation:

This is because in an hour Shelby can fix 10 pipes and will charge only $15. This means that Shelby will be able to fix 40 pipes in 4 hours and will charge $60. On the other hand, Shannon will charge $2 for every pipe fixed; hence 40 pipes will be equivalent to $80. After comparison, it becomes obvious that Shelby should be hired as the hotel will be able to save $20.
