(a) Consider the following information for a product A and a related product B:

Quantity of A traded Price of A Household Income Price of B 10,000 $1.10 $3000 $1.50 15,000 $0.90 $2500 $1.20(ii) Given that the price of product A increases by 5%, household income increases by 3% and the price of product B increases by 2%, explain and compute the effect on the revenue from product A, assume each of the changes occurs separately. (b) The demand and supply functions of wheat is given as P = 20 - 0.05Q and P = 10 + 0.05Q, respectively. Solve for the equilibrium price and quantity in the wheat market.
