If there are 180 in 2 cups then there will be 90 calories in 1 cup using 180/2. Now I order to find calories in 16 cups we multiply 16 with the the number of calories in one cup
No of cups x no of calories in 1 cup
16 cups x 90 calories
= 1440 calories.
Hence the number of calories in 16 cups is 1440
