The plumber charges $50 for the first visit plus $8 per hour of work. If the plumber’s total bill is $290, how many hours did he work?
May 18th, 2015

Let the  total number of hours he worked be y.

Charge for the first visit = $50

Charge per hour = $8

Total charge for y hours =  $ ( 8 x y) = $8y

Total charge in dollars = 50 + 8y

So 50 + 8y = 290

8y = 290 -50

8y = 240

y =  30 hours.

Hope this helps! You can ask any question if there is any issue.
