Question

Rewrite the statement and question in mathematical notation. (Let p be the price of stocks, and let v be the value of my portfolio.)
--Stock prices are rising $4,000 per year. How fast is the value of your portfolio increasing?

dp/dt= ??

Answer 1

Do you need help with this?

Answer 2

yes

Answer 3

What class is this for?

Answer 4

Math level?

Answer 5

Is this calculus?

Answer 6

It would be:
So Statement 1:
dp/dt=$4000/yr

Answer 7

and for:"how fast is the value of the portfolio v changing?"
You are being asked about a change in v as time changes, so you're solving for dv/dt

Answer 8

But since dv/dt isn't given all what you have is:
dp/dt=$4000/yr
And write a question as:
What is dv/dt? .... Since this information wasn't given.

Answer 9

All the problem wants is for you to rewrite the question "How fast is your portfolio rising?" using math. This question is really asking "what is the rate of change of the value of your portfolio?". The math translation would be : "What is dv/dt?"

Answer 10

i see, so how would i incorporate that into finding dp/dt?

Answer 11

You wouldn't. The question doesn't ask you to find it.
