1. ## Help with elasticties.

ok i have (-1/4(27)^1/3 ) * 27/q =2/q
i have no idea how they got this can some one help

2. Neither do I, what was the question? Who are they?

3. The formula for an elasticity on a continuous demand function is:

$\epsilon = \frac{dq}{dp} \times \frac{p}{q}$

Im not sure what else you think we could say with the information you provided.
