Suppose there are two consumers in the market for a good and their demand functions are as follows : ** d_(1)(p)=20-p for any price less than or equal to 15, and d_(1)(p) =0 at ant price greater than 15. ** d_(2)(p) = 30-2p for any price less than or equal to 15 and d_(1)(p)=0 at any price greater than 15. Find out the market demand function.

Answer»

Solution :It can be seen from the given demand FUNCTIONS that Consumer1 do not want to emand the goofs for any price greater than or EQUAL Rs 20 and consumer 2 do not want to demand the goods for any price greater than Rs 15.
Hence, the market demand function will be,
`d_("market")[P] = d_(1)[P] + d_(2)[P]`
`d_("demand")[P] = 20 -P + 30 -2P`
`d_("market")[P] = 50 - 3P`, for any price `lt 50 //3` and
`d_("market")[P] = 0.` any for any Price `GT = 50//3`.
