Dear teacher, Could you please help me with these question?

The Physics Club sellsE=mc²T-shirts at the local flea market. Unfortunately, the club's previous administration has been losing money for years, so you decide to do analysis of the sales. A quadratic regression based on old sales data reveals the following demand equation for the T-shirts:

q=2p²+33p(9p15).

Here,pis the price the club charges per T-shirt, andqis the number it can sell each day at the flea market.

(a) Obtain a formula for the price elasticity of demand forE=mc²T-shirts.

(b) Compute the elasticity of demand if the price is set at $9per shirt. (Round your answer to two decimal places.)

What will the revenue be?
