Question

If 5 slices of pizza cost $5:50 how much does 

Answer 1

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:

$y = (\frac{5.50}{5}) * x$

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

-two slices cost:

We substitute x = 2 in the given equation:

$y = (\frac{5.50}{5}) * 2\\y = 2.2$

Answer:

two slices = 2.2 $

-ten slices cost:

We substitute x = 10 in the given equation:

$y = (\frac{5.50}{5}) * 10\\y = 11$

Answer:

ten slices = 11 $

-half a slice cost:

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

$y = (\frac{5.50}{5}) * \frac{1}{2}\\y = 0.55$

Answer:

half a slice = 0.55 $
