The Physics Club sells E =
mc T-shirts at the local flea market. Unfortunately, the club's previous administration has been losing money for years, so you decide to do an analysis of the sales. A
quadratic regression based on old sales data reveals the following demand equation for the T-shirts.
q = -2p2 + 33p
(9 < p< 15)
Here, p is the price the club charges per T-shirt, and q is the number it can sell each day at the flea market.
(a) Obtain a formula for the price elasticity of demand for E = mc2 T-shirts.
E =
(b) Compute the elasticity
demand if
price is set at $10 per shirt. (Round your answer to two
places.)
Interpret the result.
The demand for E = mc2 T-shirts is going ?
O by about
% per 1% increase in the price.
(c) How much should the Physics Club charge for the T-shirts to obtain the maximum daily revenue?

A retailer buys Dalmatian stuffies for $6 each. (Assume that the retailer has no other variable costs). The retailer can only charge by the dollar so no
need to consider cents -- e.g., $3 is a price you could choose, $3.11 or $2.99 are not. The potential customers have the following WTP.

If she goes to the gym on any given day, it costs her (10+ F) that day, but beneÖts her 30 the next day. In other words, her "costs" are a sum of her psychic costs (10) and actual Onancial costs (F). Assume that, when indi§erent, the individual will go to the gym. (a) Suppose the potential customer is a standard exponential discounter with a discount factor of = 12. If gym membership was free (i.e. J = 0 and F = 0) would she join the gym? If so, how many days would she actually go? (b) Suppose the gym did not charge a joining fee.
