Market demand function is simply a horizontal summation of individual demand functions. Since demand function for all the 30 consumers is identical, we can write market demand simply as ‘individual demand function multiplying by a factor of 30’.
Thus: Individual demand function :
D(p)= 10-3P
Market demand function:
Md(p)=10 x 30 – 3 (30)P
= 300-90 P.
