A plumber charges a flat fee of $74 to visit a home and examine a clogged drain. The plumber charges an additional $24 spent fixing the drain. The total cost, c (in dollars), for fixing a drain that takes h hours is given by the following.
C=24h+74
Answer the following questions.
What is the total cost for fixing a drain that takes 7 hours?
To find the total cost for fixing a drain that takes 7 hours, we substitute h = 7 into the equation C = 24h + 74.
C = 24(7) + 74
C = 168 + 74
C = 242
So, the total cost for fixing a drain that takes 7 hours is $242.
