Use the compound interest formulas a= p (1 + r/n) ^nt and a= pe ^ rt to solve the problem given. round to the nearest cent. find the accumulated value of an investment of $25,000 for 4 years at an interest rate of 5% if the money is 1. compounded semiannually; 2. compounded quarterly; 3. compounded monthly; 4. compounded continuously. (if possible, explain)

Step-by-step explanation:

We know that,

where,

A = Amount after time t,

P = Principle amount,

r = Rate of interest,

n = Number of times interest is compounded per year,

t = time period in year.

Investment of $25,000 for 4 years at an interest rate of 5% if the money is compounded semiannually

Here,

P = $25,000

r = 5% = 0.05

n = 2 (as compounded semiannually)

t = 4 years

Putting the values,

Investment of $25,000 for 4 years at an interest rate of 5% if the money is compounded quarterly.

Here,

P = $25,000

r = 5% = 0.05

n = 4 (as compounded quarterly)

t = 4 years

Putting the values,

Investment of $25,000 for 4 years at an interest rate of 5% if the money is compounded monthly.

Here,

P = $25,000

r = 5% = 0.05

n = 12 (as compounded monthly)

t = 4 years

Putting the values,

Investment of $25,000 for 4 years at an interest rate of 5% if the money is compounded continuously.

where,

A = Amount after time t,

P = Principle amount,

r = Rate of interest,

t = time period in year.

Putting all the values,

It can be observed that, the frequent we compound the amount, the more we get.

other answer is correct. i had used the radius of the radius somehow. a website:

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
