How much will she need for a 15 person cake? Please show your work.

Elden [556K]

15/5 = 3

Flour = 3/8 x 3 = 9/8 = 1 1/8 cups.

Chocolate chips = 1/2 x 3= 3/2 = 1 1/2 cups.

Butter = 4/5 x 3 = 12/5 = 2 2/5 cups.

Teaspoons of salt = 4/16 = 1/4 = 1/4 x 3 = 3/4

Earthworms = 1.5 = 3/2 x 3 = 9/2 = 4 1/2 cups.

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

kupik [55]

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 $
