With the help of supply function `Q_(s) = - 10 + 2p`, answer the following quwstions:
(i) Calculate supply at price of ₹ 7, (ii) At work price, supply will be be 0, (iii) Calculate the price at which firm will be wiling to supply 50 units.

Explanation

(i) `Q_(s) = -10 + 2P`. Putting the value of price (i.e., ₹7) , we get
`Q_(s) = -10 + 2 xx 7` = 4 units
(ii) To ge the price at which supply will be zero, put 0 as value of supply:
0 =- 10 + 2p. It means , p ₹5.
(iii) To get the price, when supply is 50 units, put 50 as value of supply:
50= - 10 + 2p. It means , p ₹ 30.
