here is the original question :
the manufacture will not supply any bottles for less than 75p. when the price is £2.00, it will supply 30000 bottles and when the price is £3.00 it will supply 75000 bottles.
i take the price in £ and the bottles in thousand
use the points (0.75 ,0) (2,30) and (3,75 ) to get a graph of supply. Is it right?
AND the demand survey is given as the table below:
price (£) 1.5 2.00 2.50 3.00 3.50 4.00
percentage 89.46 37.60 16.54 7.05 3.80 1.56
i just used these figures got a graph of demand. If i want solve the problem I asked above, should I CHANGE the unit first or I can change later?? and HOW can i chage the unit??
