Extra Calories, Extra Cost

Would you still eat junk food if it cost more money? Some states have been trying out pizza and soda tax to encourage people to eat healthier. Researchers estimate that an 18% tax on these foods could reduce calorie intake by 56 calories per person per day. This would result in weight loss of about 5 pounds per person per year. Let's say someone buys a $2 slice of pizza and $1 soda once a week. How much more would that person spend per year on just those two items after the 18% tax?

ON YOUR OWN: Now think about how much junk food you buy. If you paid 18% more for it, would you buy less?
