Question

Chaz Stokes A plumber charges $90 per hour and a $50 travel fee. The total cost of his last job was $410. Use the equation 90x+50=410 to find x, the number of hours it took to complete the job.

(A) 6hr
(B) 5hr
(C) 4hr

Answer 1

The answer is C because 90 time 4 = 360 + 50 = 410

Answer 2

The number of hours it took to complete the job is 4hr.

Step-by-step explanation:

To find the number of hours it took to complete the job, we need to solve the equation 90x + 50 = 410 for x.

First, we subtract 50 from both sides of the equation to get 90x = 360.

Then, we divide both sides of the equation by 90 to get x = 4.

Therefore, it took 4 hours to complete the job, so the correct answer is (C) 4hr.
