Problem: how many calories are in a 20 ounce glass of ice tea if there is 108 calories in a 12 ounce glass
if there is 108 calories in a 12 ounce glass of ice tea, how many calories are in a 20 ounce glass
Set up a ratio: x/20 oz = 108 calories/12 oz
20 oz * (x/20 oz) = 20 oz * (108 calories/12 oz)
x = 5 * (108 calories/3)
x = 540 calories/3
x = 180 calories
Answer: there are 180 calories in a 20 oz glass of tea
