Answer 1

Using the linear function, it is found that the correct option is given by:

• On average, plumbers in the city charge a flat fee of $50, and $80 for each hour they work.

Linear functions modeling a cost have the following format:

$C(t) = C(0) + at$

In which:

• C(0) is the flat fee.

• a is the cost per unit of time.

In this problem, the cost for t hours of work is modeled by:

$C(t) = 50 + 80t$

Which means that the correct statement is:

• On average, plumbers in the city charge a flat fee of $50, and $80 for each hour they work.
