Given:

(a) P = $5000

t = 10 years

r = 4%

(b) P = $20,000

t = 25 years

r = 3%

(c) P = $5000

t = 20 years

r = 3.5%

(d) P = $5000

t = 10 years

r = 1.5%

(e) P = $5000

t = 10 years

r = 0.8%

(f) Compare the result of (a) and (c).

Required:

(a) Find the amount when interest is compound annually.

(b) To find the total amount after 25 years.

(c) Find the amount when interest is compound annually.

(d) Find the amount when interest is compound quarterly.

(e) Find the amount when interest is compound continuously.

Step-by-step explanation:

The compound interest formula is given as:


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

Where p =principal amount

r = rate of interest

n = compound frequency

t = time period in years

(a)


undefined
