Question

"The market price for Cork Oak sapling trees recently rose from $8 to $10 apiece. If revenues rose by 10% as a result, what is the original price elasticity of Cork Oak saplings? Assume demand is linear"

I have been stuck on this elasticity problem for a while now, I understand the original formulas as the percentage change in quantitiy/percentage change in price, and the several different ways to write out that equation. I do not know how to relate percentage change in revenue to price or quantity in the formula.

Explanation / Answer

% change in price= (8-10)/8*100=25%

TR=p*q

10=25*q

q=0.4

=40%

Ed=percentage change in quantitiy/percentage change in price

=-40/25

=-1.6
