Given that quantity demanded per period of time is a function of price and that the relation is expressed as: Q = 60 - 1/3 P, where Q is quantity demanded and P is the price,
(a) Find the quantity demanded when price is :
(i) N30.00;
(ii) N210.00;
(iii) NO.00.

(b) comment on (a) (ii) above.

(c) suppose the relation is now expressed as P = N (180 - 3Q); find P when:
(i) Q = 0;
(ii) Q = 60;
(iii) Q = 59.
