Stewart is hiring a plumber to fit his shower. He charges a callout fee of £18.50 and then £x per hour after that. The plumber charges him £167.00
and it takes him 9 hours.
How much does the plumber charge per hour?

The plumber charges £16.50 per hour. this is how to solve it. You minus the callout fee from the total fee which is £167.00- £18.50=£148.50. So you then divide 148.50 by the amount of hours which is 9 hours. so 148.50÷9 = £16.50
