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.
(b) We can further infer cross-price elasticity of demand for beef with respect to price of fish to be Answer for part 2
at the equilibrium.
solve b |
explain each step deeply and if theres another word for partial derative use it instead of that cuz it confuisese me a lto
