Aplumber charges $50 each visit plus $15 per hour. how many hours did the plumber work if he charged a total of $110? create an equation and solve for the number of hours the plumber worked

So, since the initial fee is $50, and every hour is $15, if h is equal to hour, the equation would be like this:

50 + 15h = 110.

Then, if we want to get the answer, we need to solve the equation.

First we pass the 50 to the other side, like this:

15h = 110 - 50

15h = 60

Then we pass the 15 dividing like this:

h = 60/15

h = 4

And we get four!

So the answer is: 4.
