Answer 1

a. Price Supply Demand

0 0 1600

20 300 1500

40 560 1400

60 780 1300

80 960 1200

100 1100 1100

120 1200 1000

140 1260 900

160 1280 800

180 1260 700

200 1200 600

Supply at price 20 is 300 i.e 1500/100 *20

a. A short run competitive equillibrium is a situation in which, given in the firms in the market, the price is such that the total amount the firms wish to supply is equal to the total amount the consumers wish to demand.

b. At 100 price 1100 flu vacines are supplied and demand and hence a point of equillibrium.
