For lunch she had 3 ounces of chicken, 2 slices of cheese, 2 slices of wheat bread, one-half tablespoon of mayonnaise, a 16-ounce glass of lemonade, and an apple for dessert. According to the chart below, which equation best represents the total number of calories she consumed during lunch?

**3. **Obj. 10 Answers-2003 #23 Calories = 3(115) + 2(45) + 2(55) + ˝ (100) + 16(110) + 70
Calories = 115 + 45 + 55 + 100 + 110 + 70
Calories = 115 + 2(45) + 2(55) + ˝ (100) + 2(110) + 70
Calories = 115 + 45/2 + 55/2 + 2(100) + 100/2 + 70
