Paha777 [63]

Answer:

$C(t)=80t+50, \text{ for }t\leq 8$ .

Step-by-step explanation:

Let C represent total daily charges in dollars and t represent time in hours.

We have been given that a plumber charges $50 for a service call plus $80 per hour.

The amount charged for t hours would be $80t$ .

The total amount charged for t hours would be $C(t)=80t+50$ .

We are also told that plumber spends no longer than 8 hours a day at any one site, this means that time t have a restriction as:

$t\leq 8$

Therefore, our required cost function would be $C(t)=80t+50, \text{ for }t\leq 8$ .
