OLga [1]

Answer:

$c(F) = 135 + 2.5F$

Step-by-step explanation:

We are given the following in the question:

Controller cost = $135

System cost = $2.50 per foot of pipeline

The total cost depends upon the length of Pole.

Let the system requires F feet of pipeline.

Total cost will be given by the equation:

$c(F) = \text{Controller cost + System cost(Feet of pipeline required)}\\c(F) = 135 + 2.5F$

is the required expression for total cost

F: feet of pipeline required

c(F): Total cost of installation
