The answer would be - C=45+25h=m
For the first hour, the electrical company charges $45 dollars. For the hours after, he charges $25 dollars. Since we do not know how many hours he worked, we put $25h in the expression. Then there is materials, which we also do not know what it cost. Therefore, the expression would be C=45+25h=m. Hope this helped :)
Answer:
C = 45 + 25(h-1) + m
Step-by-step explanation:
Note: All options are incorrect.
From the given information it is clear that
Fixed cost = $45
Hourly charges after the first hour = $25
Total number of hours = h
Remaining hours after first hour = (h-1)
Materials (m) for the job are an additional cost.
Total cost = Fixed cost + Hourly charges + Additional cost
C = 45 + 25(h-1) + m
Hence, the cost (C) to the customer if the job takes a total of h hours is C = 45 + 25(h-1) + m.
