• 5. Calories in Pink Lemonade

There are 774 calories in a cup of sugar, 65 calories in a cup of fresh lemon juice, and 137 calories in a cup of cranberry juice. (See Example 2.)

1. How many calories are in the old-fashioned pink lemonade recipe?
2. This recipe makes nine servings. How many calories are in one serving?

• Worked-Out Solution
1. To obtain the number of calories in the recipe, first, multiply the number of calories in a cup by the number of cups. Then, add.

There are about 1360 calories in the recipe.

2. Divide the number of calories by the number of servings to get the number of calories per serving.

There are about 150 calories per serving.
