1.The HSB club is selling HSB hoodies. Hoodies cost the club $10 each. One member suggests marking them up 50% and charging $15. Another points out that hoodies generally sell for $13. Another student suggests that students may want one for sentimental reasons, and thinks the price elastic of demand is fairly low, say 2. If that's the case, what would be the price of an HSB hoodie

2.Drawing from the answer in question 1, a new member of HSB suggests that the club raise the price from $20 to $25. How many hoodies must the club sell to be at least as well off as at the lower price?
