Answer:

To calculate the value of the investment at the end of 5 years for different compounding methods, we can use the compound interest formula:

A = P(1 + r/n)^(nt)

Where:

A = the future value of the investment

P = the initial principal amount (36100 dollars in this case)

r = the annual interest rate (9 percent or 0.09 as a decimal)

n = the number of times interest is compounded per year

t = the number of years

(a) Annual compounding:

For annual compounding, n = 1 (compounded once per year)

A = 36100(1 + 0.09/1)^(1*5)

A ≈ 36100(1.09)^5

A ≈ 36100(1.5386246)

A ≈ 55537.33 dollars

(b) Semiannual compounding:

For semiannual compounding, n = 2 (compounded twice per year)

A = 36100(1 + 0.09/2)^(2*5)

A ≈ 36100(1.045)^10

A ≈ 36100(1.6288946)

A ≈ 58785.46 dollars

(c) Monthly compounding:

For monthly compounding, n = 12 (compounded twelve times per year)

A = 36100(1 + 0.09/12)^(12*5)

A ≈ 36100(1.0075)^60

A ≈ 36100(1.4579742)

A ≈ 52562.43 dollars

(d) Daily compounding:

For daily compounding, n = 365 (compounded 365 times per year)

A = 36100(1 + 0.09/365)^(365*5)

A ≈ 36100(1.000246575)^1825

A ≈ 36100(1.4497384)

A ≈ 52292.54 dollars

Therefore, to the nearest cent, the value of the investment at the end of 5 years for different compounding methods is as follows:

(a) Annual: $55,537.33

(b) Semiannual: $58,785.46

(c) Monthly: $52,562.43

(d) Daily: $52,292.54
