Compound interest formula is
A = P[1+(r/n)]^(nt)
A is the final amount
P is what Mr Lee put into the bank
r is the annual interest rate (in decimal, so in this question its 0.395)
n is the number of times interest is compounded (quarterly means 4 times per yeae)
t is number of years Mr Lee leaves the money inside
For second part, compound interest due to higher returns
