Question
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 <p< 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.
