Question

A mechanic charges her clients for her services on a relation of the total bill f (h) to the number of hours worked h. The best interpretation of 125 In the function is f (h) = 125 + 20h.

A: she charges a flat fee of $125

B: she charges $125 for a tire change

C: she charges $125 per day

D: she charges $125 per hour ​

Answer 1

A: she charges a flat fee of $125

Explanation:

The $125 is a fee that is not associated with hours worked. There is insufficient information in the problem statement to tell the reason for that fee, except that we know it is not the hourly charge. Perhaps the best assumption is that it is a flat fee.

Apparently, she charges a flat fee of $125.
