chapter 4 graphs

I have only a very old of the BPP text so I don’t know if the graphs in Chapter 4 are the same as you are talking about.

In my copy there are two graphs, both of a demand curve or schedule.Both show that as the price falls (ie you reduce the reading on the vertical axes) demand increases. So in Figure 1, at a price of 6 there is a demand of 1kg, but by the time price is reduced to 2, demand will have increased to 8. This is normal behaviour: lower prices usually means that more items will sell.

Figure 2 is essentially the same except that the demand line is not straight. There is no particular reason why it should be linear. Again, lower prices mean more units are demanded.

Look on pages 116 and 117 of the Opentuition notes for our demand curves and listen to the lecture.

Did you listen the lectures?

If you didn’t understand the BPP text, the OT notes, my reply above or the OT lectures then I suggest you try Googling ‘demand curve’
