A plumber charge $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

Respuesta :

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.

Plumber's total charge: C(x) = $50 + ($15/hr)x, where x is the # of hours worked.

Setting C(x) = $110, we have $110 = $50 + ($15/hr)x

Subtracting $50 from both sides results in $60 = ($15/hr)x, which comes

out to x = 4. The plumber worked for 4 hours to earn $110.
