the question:

There are large numbers of potato farms around a town that consumes all their produce. Potato farming requires 1D kg of fertiliser and 5 hours of labour to produce one ton of potatoes. Fertilizer costs 5 TLfkg, labour costs ED Tthom'. All farms also faoe a transportation post of [1.5 TLfkg when the!\"r buv fertiliser; except farm .4 which is situated very close to the fertiliser plant and therefore faces no transportation charge. Assume that farming land is limitedI and no farm can produce more than we tons. a] Derive the supplilir curve for farm A. Derive the supplilir curve for all the other farms. b] What is the equilibrium price? c} Does an!\"r farm earn economic rent? d] Does farm A affect the price of potatoes in the market? If not, why not? e} Suppose that there is no land limit. What will the equilibrium price be? f} Will farm A affect the price when there is unlimited farming land
