A cоmpаny оf а reаlly cоol bandana identified two consumer segments with equal size. Say 1000 consumers in each segment. Consumers in segment 1 are willing to purchase the product at $120 this season, or at $70 next season. Consumers in segment 2 are willing to purchase the product at $30 in this season and $40 in the next. Assume that consumers will only purchase the product once and that the bandana costs pennies to make. Find the optimal prices to set this season and the next (assuming consumers know the prices). What is the price you should set in the current season?
