Aplumber charges a flat fee of 77$ to visit a home and examine a clogged drain. the plumber charges an additional 24$ per hour spent fixing the drain. the total cost, c (in dollars), for fixing a drain that takes h hours is given by the following.

c=77+24h

answer the following questions.

(a) what is the total cost for fixing a drain that takes 7 hours?

(b) if the plumber charges a total of 365 $ how long did he take to fix the drain

A. 77+24(7)=$245

B. 12 hours.

Step-by-step explanation:

For b, what you need to do is minus 77 from 365. Then divided by 24.

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
