Elasticity of Demand

apple + orange = apple + orange

cannot be simplified

Just want to give you the heads up: This is the homeport of Austrian Economics, which praxeologically, a prioristically disproves these times of economics (ie- through logic and statements that cannot be disproven)

People here tend to reject any of these types of graphs/tables/equations that assume perfect knowledge of the market, although some of us received this training in schooling, like I did for the AP Econ tests

Complete the following table. Use the mid-point formula to calculate the coefficients. In column 4, determine whether demand is elastic, inelastic, or unit elastic based on the coefficient calculated.

For elastic=1, unit- 45deg angle;

Inelastic, <1- more vertical than horizontal

Elasiticity is really the [(delta)%QD]/[(delta)%P}

I believe your math is incorrect… based on the figures you have for elasticity, the type is correct- and the TR is correct, but where you have 2.33, it is (delta)QD=4-3, average QD= (4+3)/2, they do with the ones just above- I calculated 1.8someodd for that instead of 2.33

The only one I see the math being wrong is the one you labled unit elastic- (1/5.5)/(1/4.5)=/=1
