Question: If you invest P dollars in a bank account at an annual interest rate of r%, then after t years you will have B dollars, where
B = P(1 + (r/100))t
(a) Find dB/dt, assuming P and r are constant. In terms of money, what does dB/dt represent?
(b) Find dB/dr, assuming P and t are constant. In terms of money, what does dB/dr represent?
