The Los Angeles Department of water and Power (DWP) supplies water and electricity to residents of the city. Water usage is measured in hundred cubic feet (HCF). The cost function C (x) gives the cost (in dollars) for using x HCF. Write a summary in words for the symbolic statement C(110) = 264.
The cost for using HCF of water is $

The cost for using 110 HCF of water is $264

Step-by-step explanation:

From the question, we understand that:

C is a function of x

i.e. C = f(x)

Or

C(x)

Such that x represents the amount of water and c represent the cost of x amount of water

So, for C(110) = 264

The first will contain the amount of water used.

In this case, amount used is 110 HCF

While

The second will contain the cost of the amount of water used.

In this case, the cost is $264

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3
