use the difference quotient, w/h=0.01 and estimate the instantaneous rate of change.

#10. P(r)=100(1+r)^2 where r=0.12

Can you show me how to set up to solve? I do not seem to grasp the idea of the letters and the corresponding #'s and where to place.

I don't have the actual answer for this problem, book only gives odds.
