A recipe requires 2 3/4 cups of sugar to make a dessert dish for 20 people. How much sugar is needed to make the recipe for 36 people?
Answer provided by our tutors
let 'x' represent the number of cups of sugar to make the recipe for 36 people
2 3/4 = (2*4 + 3)/4 = 11/4
(11/4) : 20 = x : 36
by solving we find:
x = 99/20
x = 4 19/20 cups of sugar
