elasticity E(p) as function of p = 7, given x=f(p)=600/(p+4)

[beachbunny619]

x=f(p)=600/(p+4) ; p=7
Enter the elasticity E(p) as a function of p

I got 4p/p+4 but that's not right...

 

[stapel]

x=f(p)=600/(p+4) ; p=7
Enter the elasticity E(p) as a function of p

If p is fixed as having a value of 7, how is anything else going to be a "function" of p?

For what do x, p, and f(p) stand? How does E(p) relate to some or all of these?

How did you arrive at your answer?

Please be complete. Thank you!

I did the quotient rule

I will guess that the above is your reply to my third question...? I'm sorry that you don't remember what your steps were and can't find your scratch paper. Please re-work the exercise, to remind yourself of what you did, and then reply with a complete explanation of how you arrived at your answer.

When you reply, please also include all of the other missing information. Thank you!

(p+4)[600]-(600)[p+4]
(p+4)(1)-(600)(1)
P+4-600???

 

[Deleted member 4993]

(p+4)[600]-(600)[p+4] = 0

Beachbunny - to repeat mmmMark - you need to review algebra before you do these problems

(p+4)(1)-(600)(1)
P+4-600???

Can someone just help me with the problem...

They're probably confused by it. You have \(\displaystyle f(p)=\frac{600}{p+4}\), but then state enter E(p) as a function of p. Is it E(p) or f(p)?. p is given as a constant, therefore, how can we express a function in terms of it?. Are you sure there are no typos and the entire problem has been given?. The reason I did not assist in the first place was I did not understand the problem statement.
