Hi John
This question drove me nuts today! How is ‘a’ calculated if all you have is b=0.0004 & Maximum Demand is 1,000,000. There was no mention of existing selling price and corresponding demand. Thanks.

Maximum demand is when Price=0
P=0
a=0.0004
Q=1000000
P=a-bQ
0=a-(0.004*1000000)
0=a-400
a=400

But then what is the need for information about cost calculation?I mean information for marginal cost calculation.

I suppose, this is for 1 mln demand,and we need further calculations as usual, find q, then find profit maximising price?

I did use the 400 as outlined above, and after working out variable cost, i plugged it into MC=MR=a-2bQ formula. I can’t remember what my optimum price and demand worked out as though.
