Answer:
Step-by-step explanation:
Given:
- Investment P = $20000
- Time t = 7 years
- Interest rate r = 5.5% = 0.055
a. compounded semiannually, n = 2
- [tex]A = P*(1 + r/n)^{nt} = 20000(1+0.055/2)^{2*7} = 29239.88[/tex]
b. compounded quarterly, n = 4
- [tex]A = P*(1 + r/n)^{nt} = 20000(1+0.055/4)^{4*7} = 29315.30[/tex]
c. compounded monthly, n = 12
- [tex]A = P*(1 + r/n)^{nt} = 20000(1+0.055/12)^{12*7} = 29366.44[/tex]
d. compounded continuously
- [tex]A = Pe^{rt}=20000*e^{0.055*7}=29392.29[/tex]
