The first thing we must do for this case is to define variables.

We have then:

x: number of slices

y: total cost

We write the linear function that relates the variables.

We have then:

[tex] y = (\frac{5.50}{5}) * x
[/tex]

Then, we evaluate the number of slices to find the total cost.

-two slices cost:

We substitute x = 2 in the given equation:

[tex] y = (\frac{5.50}{5}) * 2

y = 2.2
[/tex]

Answer:

two slices = 2.2 $

-ten slices cost:

We substitute x = 10 in the given equation:

[tex] y = (\frac{5.50}{5}) * 10

y = 11 [/tex]

Answer:

ten slices = 11 $

-half a slice cost:

We substitute x = 1/2 in the given equation:

[tex] y = (\frac{5.50}{5}) * \frac{1}{2}

y = 0.55 [/tex]

Answer:

half a slice = 0.55 $
