Qd=400-(2P+T), Qs=100+3P. and T=15. (P is the price recieved by sellers and P+T is the price paid by buyer)




Please sove these problems. Actually i could find the solution from internet like yahoo answer or some websites...

.but I'd like you to teach me more more more about that in detail so that i can finaly understand the concept completely.

Explanation / Answer

If the tax is less than $10, there will be a price at which both John and Willa will still benefit from the lawn-mowing arrangement. If the tax is $10, a price can be set that will leave John and Willa neither better off nor worse off from the lawn-mowing arrangement. If the tax is greater than $10, all possible prices will leave at least one of the parties worse off from the lawn-mowing arrangement.

by selecting the level of output at which marginal revenue is equal to marginal cost. If MR > MC, profit will increase if the firm increases Q. If MR < MC, profit will increase if the firm decreases Q.

Prior to the tax , the equilibrium price would be 60 dollars and equilibrium quantity would be 280 dollars .after the tax imposed P , the price received but sellers would be 57 dollars . the price paid by the buyers would be 72 dollars . the quantity sold would be 271 dollars. The new answer shows three oblivious facts . First buyers pay more with a tax . Second sellers receive less with a tax . thord the size of the market shrinks when a tax is imposed on a product
