DIA [1.3K]

Answer:

$C=75t+100$

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

$C=mt+b$

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

$b=\$100$ ----> set fee

we have the ordered pair (2,250)

substitute the given values

$250=m(2)+100$

Solve for m

$2m=250-100$

$2m=150$

$m=\$75\ per\ hour$

The linear function is equal to

$C=75t+100$
