An electrician charges a set fee of $100 for every house call and then charges an additional hourly rate. one day, the electrician earned a total of $250 for a 2 hour job. write an equation for the function c(t), representing the total cost of the electrician's services if the electrician spends t hours at the house working. plz answer asap free extra points

Step-by-step explanation:

Let

C(t) ---->the total cost of the electrician's services in dollars

t ---> the number of hours

we know that

The linear function in slope intercept form is equal to

where

m is the slope or unit rate

b is the y-intercept or initial value

In this problem we have

the y-intercept is equal to

----> set fee

we have the ordered pair (2,250)

substitute the given values

Solve for m

The linear function is equal to
