Answer:

3 hours

Step-by-step explanation:

To find the number of hours the plumber was at the house, we need to solve for x.

22x + 50 = 116

22x = 116 - 50

22x = 66

22x/22 = 66/22

x = 3

EXPLANATION:
Money charging per hour = $22
Additional charge= $50
Final bill= $116
Final bill removing the additional charge= $(116 - 50) = $66
Time the plumber was in the house= (66/22)hr = 3hr.

ANSWER: The plumber was there for 3 hours.
