One recipe for pancakes says to use 11 2 cup of mix to make 7 pancakes. how much mix is needed to make 35 pancakes?20 points

7 1/2 cups

Step-by-step explanation:

1 1/2 cups           x cups

7 pancakes      35 pancakes

 using cross products

1 1/2 * 35 = 7 * x

change 1 1/2 to an improper fraction  (2*1+1)/2 = 3/2

3/2 * 35 = 7x

105/2 = 7x

divide each side by 7

105/2 * 1/7 = x

15/2 =x

change back to a mixed number

2 goes in to 15 7 times with 1 left over

7 1/2 cups

16.80 times .20= 3.36
