**
compound interest formula: A=P(1+r)^n, P=initial amt, r=interest rate per period, n=number of periods, A=amt after t periods
..
After 10 years of semi annual compounding at 7% interest rate
A=3000(1+.07/2)^10*2
A=3000(1+.035)^20
A=3000(1.035)^20≈5969.37
After 16 years(4 more years of quarterly compounding at 7.25% interest rate)
A=5969.37(1+.0715/4)^4*4
A=5969.37(1+.018125)^16
A=5969.37(1.018125)^16≈7956.94

..
Value of the account after 16 years=$7956.94
