Question 622147
how much money would be in an account after 5 years if an original investment of $6500 was compounded quarterly at 4.5%?. compare this amount to the same investment that was compounded daily. round to the nearest cent.
**
Compound Interest formula: 
A=P(1+i)^n, P=initial investment, i=interest rate per period, A=amount after n periods
For given problem:
compounding quarterly
P=6500
i=.045/4 (annual interest/number of compounding periods per year)
n=5*4=20 periods
A=6500(1+.045/4)^20
using calculator
A=8129.88
..
compounding daily 
P=6500
i=.045/365 (annual interest/number of compounding periods per year)
n=5*365=1825 periods
A=6500(1+.045/365)^1825
using calculator
A=8139.98
..
compounding daily gives about $10 more over a 5-year period
