# I'm working with an elasticity problem where q=3.73p^-0.25 JA:

### Customer Question

I'm working with an elasticity problem where q=3.73p^-0.25
Customer: I determined the derivative dq/dp to be 0.9325 * p^-1.25
JA: Is there anything else important you think the Tutor should know?
Customer: but I can't seem to solve for p in order to determine elasticity
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the \$5 fully-refundable deposit now. While you're filling out that form, I'll tell the Tutor about your situation and then connect you two.

A given product has a demand that is expressed by the owing equation
q=3.75p^-0.25
Where p=price and q=quantity
Find whether the demand is elastic or inelastic using
E=(p/q) × the derivative dq/doI derived dq/do to be
0.9325p^-1.25 but that left me with some pretty obfuscated algebra and I could not resolve p in order to sub in test numbers for elasticity to see if they were greater OE less than 1 (elastic or non elastic)
I'd like to learn how to solve the equation.

Is that enough to go on?

As your reply did not use Calculus but only arbitrary plug in values it does not help. I explicitly provided the derivative to plug back into the formula for E
E= P/Q * (dQ//dP) without the
Without the work this did not help and in the meantime I was able to solve for E and derived a different answer than you.
Would you like to see the work?

So believe this is incorrect sinc it is not a linear equation

Okay

Okay, I see there is not going to be a response. I will never use this site ever again since I did not get a correct answer and I clearly expressed the methodology was calculus not arbitrary values.
