Sir in chapter 7 example 6 you have taken selling price as 120 but in question it is 100 so where from did u get this 120? Is it a mistake?
Ask the Tutor ACCA PM
Answer not correct.

120 is the price at which the demand will be zero, which is what is required for the price demand equation.
I work through this example (and all examples) in the free lectures and explain.
(You should not use the lecture notes without watching the free lectures. They are only lecture notes, and it is in the lectures that I explain and expand on the notes.)
