Levart [38]

Answer:

you need 6 cups of raisins, 4 cups of granola and 8 cups of blueberries.

Step-by-step explanation:

<u>Step 1: Find how much raisins are needed</u>

<em>For 4.5 cups of fruity granola, we need 1.5 cups of raisins</em>

<em>For 18 cups of fruity granola, we need y cups of raisins</em>

4.5 : 1.5

18 : y

<em>Cross multiply</em>

4.5y = 1.5 x 18

y = 27/4.5

y = 6 cups of raisins

<u>Step 2: Find how much granola is needed</u>

<em>For 4.5 cups of fruity granola, we need 1 cup of granola</em>

<em>For 18 cups of fruity granola, we need y cups of granola</em>

4.5 : 1

18 : y

<em>Cross multiply</em>

4.5y = 18

y = 4 cups of granola

<u>Step 3: Find how much blueberries are needed</u>

<em>For 4.5 cups of fruity granola, we need 2 cups of raisins</em>

<em>For 18 cups of fruity granola, we need y cups of blueberries</em>

4.5 : 2

18 : y

<em>Cross multiply</em>

4.5y = 2 x 18

y = 36/4.5

y = 8 cups of blueberries

Therefore, in order to make 18 cups of fruity granola, you need 6 cups of raisins, 4 cups of granola and 8 cups of blueberries.
