Over all age groups for Americans, the consumption of chil peppers is:

 6.3 pounds per person in 2007
Problem 1: Assuming the situation is linear, how many pounds of chili peppers would a person eat in 2050?
Problem 2: Assuming the situation is exponential, how many pounds of chili peppers would a person eat in 2050?
