Sagot :
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 $
