Answer:

C) C(x) = 5 +0.25x

Step-by-step explanation:

Let

C(x) ---> the total cost monthly

x ---> is the number of hours in a month

we know that

he linear equation in slope intercept form is given by

[tex]C(x)=mx+b[/tex]

where

m is the slope or unit rate

b is the y-intercept or initial value

In this problem we have

The slope is equal to

[tex]m=\$0.25\ per\ hour[/tex]

The initial value or y-intercept is equal to

[tex]b=\$5.00[/tex]

substitute

[tex]C(x)=0.25x+5.00[/tex]
