If 5 slices of pizza cost $5.50, how much does each of the following cost?

- Two slices
- Ten slices
- Half a slice

**two slices = 2.2 $
**
**-ten slices cost: **
We substitute x = 10 in the given equation:
[ y = (\frac{5.50}{5}) * 10
y = 11 ] ; 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:
y = ( 5 5.50 ​ ) ∗ x
Then, we evaluate the number of slices to find the total cost.
**-two slices cost: **
We substitute x = 2 in the given equation:
[ y = (\frac{5.50}{5}) * 2
y = 2.2 ]

The cost of two slices of pizza is $2.20, ten slices cost $11.00, and half a slice costs $0.55. Each slice costs $1.10. This was calculated based on the total cost of 5 slices being $5.50.
