Math Problem Statement
The demand relation for beef takes the form of
QB = 210 − 4.2PB + 0.6PF + 1.9I
where PB is the price of beef, and PF is the price of fish, and I is the income. At one equilibrium, QB = 590.4, PB = 49, and PF = 67.
(a) We can infer that the income elasticity of demand for beef is Answer for part 1 at the equilibrium.
