For a service call, a furnace technician charges an $85 initial fee, plus $50 for each hour he works. a) Write an equation represent the total cost, C dollars, for t hours of work.

b) If the repair takes 2 hours, how much will the customer be charged?

c) If a customer was charged $210, how long was the service call?

d) How would the equation change if the technician charges $95 initial fee plus $40 for each hour he works? Will the technician be making more for working 3 hours with this change?

they disappear if your absent from to long. i found out that the hard way.

step-by-step explanation:

brainliest lol i just need one more brainliest.

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.

the height of the surface increases from the center out to the sides of the road

it is c!

it's undefined because anything multiplied by 0 is 0. that said, 7 days is 168 hours
