      I’m with you.. It’s a part with the paradox – seems obvious yet so obscure and elusive

        Bad times my friend. Second time around I’m understanding it more. Whether that has something to do with not doing two papers at once which isn’t diluting my time or not… We shall see.

    Dear John,

    For example 4, may I ask what would be the action if, a, was left as a positive figure and not 0?

    Many thanks

      I am not sure what you mean, because a is not zero.a is the selling price that would result in the demand being zero.
      As the selling price is reduced the demand will increase.

    Hi John,

    Example 4, page 28. I’m not quite sure how you got 18.4 by adding 6.4 to both sides of the equation. Can you clarify please?

    Thanks
    Carmel

      They sell 16,000 units at a price of $12.

      The maximum price (a) is the price at which the demand is zero – i.e. demand lower by 16,000.

      For every 2,500 lower demand, the price is increased by $1. So for 16,000 lower demand, we need to increase the price by 16,000/2,500 x $1 = $6.40

      So maximum selling price (a) = 12 + 6.50 = $18.40

    I’m stuck on example 6 chapter 7. Selling price 拢100 p.u demand 20,000 per annum. For every 拢2 change in selling price demand will change by 2000 units. On looking at the answer P=120-0.001Q I get where the 0.001 comes from but where do you get the 120 from?

    Thanks

      The best way to remember it is : a = current selling price + b (current demand)

        Sorry can you expand please selling price is 拢100 plus current demand? Isn’t that 20,000 pa because b = 拢2/2000.

      • vikki says

        April 20, 2014 at 10:20 am

        I’ve woken up sorry I didn’t multiply 0.001 with demand of 20000 to give 20+100=120

    Hi i have a lil doubt… minus minus is plus …so how we got -2500 b …we supposed to add 16000 and 13500 and get -29500 instead

      Minus minus is indeed a plus.

      However, we are taking minus 16,000 plus 13,500.
      -16000 + 13500 = -2500

      (look again – it is minus 16000!)

    Conventional way of calculating the slope of the demand curve is Changes in Quantity/Changes in Price. Why does ACCA Text use Changes in Price/Changes in Quantity? However, I do understand a slope of a straight line is Changes in Y/Changes in X.

      I don’t know why you say the conventional way of calculating the slope is change in demand/change in price.

      For the price elasticity of demand, then it is demand / price, but the conventional price/demand equation is P = a – bQ for which the slope is b which is change in price/change in demand.

    Example 5 says reduction in price causes increase in demand rather than increase in price and decrease in demand. So shouldn’t the equation be 10-0.01Q??

      October 17, 2012 at 1:37 pm

      @musema, Because we assume that the relationship is linear, a reduction in price causes an increase in demand, and an increase in price causes the same reduction in demand.
      The equation cannot be P = 10 – 0.01Q, because that would mean that the current demand of 2000 would give a selling price of 10 – 20 = -10!!!
      The lecture is correct.

    As I see, “Price elasticity” topic is not mentioned in the videos to chapter 7. Or I missed it?

      @natasya, You are right – it is not mentioned. I will re-record it shortly but until then you can find it in the course notes.
