what the monkey is "elasticity of demand"??

anonymous · Answer

% change in demand/ % change in price

anonymous · Answer

the derivative?

anonymous · Answer

picture in wikki suggests it is the slope of the normal line, does that sound right?

anonymous · Answer

no im not really sure

anonymous · Answer

i am watching a youtube video

anonymous · Answer

oh i see you need to compare the two changes

anonymous · Answer

oooh learn something new every day

anonymous · Answer

this is two separate questions right? one for $p=15$ and another for $p=50$

anonymous · Answer

looks like it is $D'(p)\times \frac{p}{D(p)}$
