Suppose there are two consumers in the market for a good and their demand functions are as follows: d1(p) = 20 – p for any price less than or equal to 20, and d1(p) = 0 at any price greater than 20. d2(p) = 30 – 2p for any price less than or equal to 15 and d1(p) = 0 at any price greater than 15. Find out the market demand function.
