Answer:

0.75

Step-by-step explanation:

Using the equation

y=mx

where y is the cost, m is constant and x is variable representing packages

8.85=15x

5.1=10x

Subtracting equation 2 from 1 then

5x=3.75

x=3.75/5=0.75

x=0.75

The constant of proportionality is 0.75

Leon is using the recipe shown.
stira [4]

He will use 11 and half cups of olive oil to use with 1 teaspoon of cinnamon.

Step-by-step explanation:

Given,

Olive oil used in recipe = 23 cups

Cinnamon used in recipe = 2 teaspoons

Ratio of cinnamon to olive oil in recipe = 2:23

Cinnamon Leon has = 1 teaspoon

Let x be the olive oil.

Ratio of available cinnamon to olive oil = 1:x

Using proportion;

Ratio of cinnamon to olive oil in recipe :: Ratio of available cinnamon to olive oil

2:23::1:x

Product of extreme = Product of mean

2*x=23*1\\2x=23

Dividing both sides by 2;

\frac{2x}{2}=\frac{23}{2}\\x=11.5

11.5 can also be written as 11\frac{1}{2}

He will use 11 and half cups of olive oil to use with 1 teaspoon of cinnamon.
