(a) If rm 1's supply function is 51(p) = p, firm 2's supply function is 52(p) = 2p, and firm 3's supply function is 53(p) = 3p, then draw individual supply functions and the market supply function. Write an equation of the market supply function. (b) If rm 1's supply function is 5109) = 2p, firm 2's supply function is 32(1)) = p l, and firm 3's supply function is 33013) = 0, then draw individual supply functions and the market supply function. Write an equation of the market supply function. (c) If firm 1's supply function is 31(1)) = 3p 12, rm 2's supply function is 32(p) = 2p 8. and firm 3's supply function is 53 (p) = p 4, then draw individual supply functions and the market supply function. Write an equation of the market supply function. (d) There are 300 firms on the market. Each one of the 200 firms has supply function s1(p) = 2p - 8. Each one of the remaining 100 firms has supply function s2(p) = p - 3. Draw two different individual supply functions, and write an equation of the market supply function
