Question

Pete's Plumbing charges $95 for a service call and $25.75 per hour for repairs. Mike's Plumbing charges $50 for a service call and $40.75 per hour. How many hours would it take for the cost to be the same for both companies?

Answer 1

3 hours

Explanation:

Step one:

given data

Pete's Plumbing charges $95 for a service call and $25.75 per hour

let the number of hours be x

and the total charges be y

y= 25.75x+95---------------1

Mike's Plumbing charges $50 for a service call and $40.75 per hour.

let the number of hours be x

and the total charges be y

y= 40.75x+50------------2

Step two:

equating the two expressions above we have

25.75x+95=40.75x+50

40.75x-25.75x=95-50

15x=45

divide both sides by 15

x= 45/15

x=3 hours
