Katarina is drinking a bottled soda. Her friend, Asha, tells her that the soda is loaded with calories. Katarina glances at the nutritional label and says, “It’s only 120 calories.” Asha responds, “You have to do some math. In that bottle, there are actually 240 calories.” Asha is correct. Katarina is confused. “How is that possible?” she asks Asha. What is Asha’s MOST likely explanation? What math does Katarina need to do to correctly interpret the label?
