Q = 800 - 130PP + 2A - 30Ps + 6I
where Q = unit sales of pretzels, PP = price of pretzels in dollars, A = advertising expenses, Ps = price of soda pop sold at your stand in dollars, and I = per capita income of customers inthousands of dollars. You are currently charging $2 per pretzel, spending $200 in advertising, charging $1 for a soda pop, and per capita income is $22,000.
a. Compute price elasticity, advertising elasticity, income elasticity and cross-price elasticity.
b. You are currently paying $1 to produce a pretzel (including cost for dough cost to bake, and wrapping). Is this the profit-maximizing price? Explain/show your math.
