Samantha is making gluten free brownies for the family picnic. If the recipe calls for 2 ½ cups of cocoa to serve 4 people, how many cups will he need if there will be 60 people at the picnic?
Samantha's recipe calls for 2 ½ cups of cocoa to serve 4 people. Or, in other words,
-> 4 people require 2 ½ cups of cocoa.
-> 1 person would then require (2 ½) / 4cups of cocoa, which is 0.625 cup of cocoa.
-> So 60 people would require 0.625 x 60 cups of cocoa = 37.5 cups of cocoa.
Answer: 37.5 cups of cocoa.
