Answer:
3 hours
Step-by-step explanation:
We know that Comcast charging $25 for coming to your house and $50 for the parts use is fixed. Comcast also charges $34 for every hour, which is what we don’t know: how many hours it took to fix the table.
Knowing this information, we can set up this equation:
25+50+36h=183
(h=hours)
And we can start solving:
25+50+36h=183
75+36h=183
Move 75 to the other side to combine like terms
36h=183-75
36h=108
Divide both sides by 36 to isolate h
h=108/36
h=3
