Hi Profesor,
For example 3 under the midpoint method, if two slices of pizza are $4, wouldn't the price for one just be $2? Therefore, shouldn't the total revenue be 2times 10? Thanks!

prob super picky question, but i believe ur best suited to answer this since you've been grading these ap exams for a long time!
in the lecture, you wrote (4-5)/4 = | -1/4 |, which, in itself, is not a true mathematical statement. though most people will understand how the absolute values factors into elasticity of demand, do graders take off points bc of small mathematical mishaps?

In example 2, since Q1=200, doesn't e equal 1? If so, isn't this product's total revenue supposed to remain the same? So how comes the total revenue decreased after the rise in price?
Thank you!

Professor,
I saw a different function in text book. E of demand= (change in Q/((Q1+Q2)/2))/change in P/((P1+P2)/2). And I plugged in some real numbers and got different results from the function you talks about in the lecture. Which one is right? Thanks!

In the factor of time that determines elasticity demand, is it very similar to the substitute? Because people tend to have more substitute over time.

1. What is two ways of calculating PED contradict each other? Like one proves it's elastic and the other one proves it's not.
2. If E is 1, is it neither elastic nor inelastic?
Thank you!

So for questions where the elasticity is asked, there are two possible answers? One from the regular elasticity formula and one from the midpoint method..will both be marked correct?

Why are there two different values for elasticity when using the midpoint formula as opposed to using the price elasticity of demand formula? What do each of the numbers mean? Which method is more accurate?
