a sum of 1000 invested at an jntrest rate 12% per year. Find the amounts in the account after 3 years if intrest is compounded annualy, semiannually, quarerterly, monthly, and daily.

Given Information:

Annual interest rate = r = 12%

Principal amount = P = $1000

Number of years = t = 3  

Required Information

Accumulated amount = A = ?

Annual compounding = A = $1404.93

Semi-annuall compounding = A = $1418.52

Quarterly compounding = A = $1425.76

Monthly compounding = A = $1432.30

Daily compounding = A = $1433.14

Step-by-step explanation:

The accumulated amounts in terms of compound interest is given by  

Where  P is the initial amount invested and A is the accumulated amount.

For annual compounding:

i = 0.12

N = 3

For semiannually compounding:

i = 0.12/2 = 0.06

N = 2*3 = 6

For quarerterly compounding:

i = 0.12/4 = 0.03

N = 4*3 = 12

For monthly compounding:

i = 0.12/30 = 0.004

N = 30*3 = 90

For daily compounding:

i = 0.12/365 = 0.0003287

N = 365*3 = 1095

you didn't give me the choices, so i will just give you the graph so you can look at your choices and choose the right one.

80 the answer is 80
