Question

The cost of putting in automatic sprinklers for a lawn largely depends upon the length of Poole that must be laid. The controller costs $135 and the system costs $2.50 per foot of pipeline. Which equation could be used to find the cost, c, of a system that requires F feet of pipeline?

Answer 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
