Answer:
1, 2 and 3
Step-by-step explanation:
Let
t -----> the number of hours the job takes
C(t) -----> the total cost for the service
we have
[tex]C(t)=125t+95[/tex]
This is the equation of a line in slope intercept form
where
The slope m is equal to [tex]m=125\ \frac{\$}{h}[/tex]
The y-intercept is the point (0,95) ---> The cost is $95 for the value of t equal zero (fee)
therefore
The statements that are true
1 a house call fee costs $95
2 the plumber charges $125 per hour
3 the number of hours the job takes is represented by t
