Answer provided by our tutors
let 'x' be the number of cups of brown sugar needed for 13 dozen cookies
3/4 cups of sugar for 6 dozen of big cookies
x cups of sugar for 13 dozen of cookies
we have the following proportion
3/4 : 6 = x : 13
by solving we find
x = 13/8 cups
x = 1 5/8 cups of brown sugar
x = 1.625 cups of brown sugar
