The Physics Club sells E = mc² 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 sps 15).
Here, p is the price the club charges per T-shirt, and g is the number it can sell each day at the flea market.
(a) Obtain a formula for the price elasticity of demand for E = mc? T-shirts.
E =
(b) Compute the elasticity of demand if the price is set at $9 per shirt. (Round your answer to two decimal places.)
Interpret the result.
The demand for E = mc2 T-shirts is going ?
v 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?
$
What will the revenue be?

A house’s electricity use, over a one day period, is modelled by E(t) = t + sin(t) (kW), where t is in hours. What is cumulative energy consumption of the household over the period, approximately? Include units.
Two types of barrel units were in use in the 1920s in the United States. The apple barrel had a legally set volume of 7056 cubic inches; the cranberry barrel, 5826 cubic inches. If a merchant sells 30 cranberry barrels of goods to a customer who thinks he is receiving apple barrels, what is the discrepancy in the shipment volume in liters (L)? Give your answer as a positive number.
