2) When the price of a certain product is $40, then 25 items can be sold. When the price of the same product costs $20, then 185 items can be sold. On the other hand, when the price of this product is $40, then 200 items will be produced. But when the price of this product is $20, only 100 items will be produced. a) Find the supply and demand functions for this product (assume for simplicity that the functions...
