(adsbygoogle = window.adsbygoogle || []).push({}); Differential eq problem (urgent)

I have the following question which I was to answer:

"The rate of increase of the rate of inflation is decreasing". Write this sentence in terms of derivatives of average prices.

My answer was:

Let p=price

t=time

Therefore rate of change of price = dp/dt (Inflation) = I

Therefore rate of change of Inflation = I'

Therefore I'= (d^2p)/(dt^2)

Since the rate of change of Inflation is decreasing;

I' = - (d^2p)/(dt^2)

I just wanted to check whether my answer is correct.

Please help.
