Math Problem Statement
A software entertainment company recently ran a holiday sale on its popular software program. Using data collected from the sale, it is possible to estimate the demand corresponding to various discounts in the price of the software. Assuming that the original price was
$4141,
the demand for the software can be estimated by the function
q equals 3 comma 836 comma 000 p Superscript negative 2.228q=3,836,000p−2.228,
where p is the price and q is the demand. Calculate and interpret the elasticity of demand.

Part 1
What formula should be used to compute the elasticity of demand, E, if q is demand at a price p?
A.Upper E equals negative StartFraction p Over q EndFraction times StartFraction dq Over dp EndFraction
Upper E equals negative StartFraction p Over q EndFraction times StartFraction dq Over dp EndFractionE=−pq•dqdp
Your answer is correct.
B.Upper E equals StartFraction p Over dp EndFraction times StartFraction q Over dq EndFraction
Upper E equals StartFraction p Over dp EndFraction times StartFraction q Over dq EndFractionE=pdp•qdq
C.Upper E equals p times dq
Upper E equals p times dqE=p•dq
D.Upper E equals q times dp
Upper E equals q times dpE=q•dp
