Using the cash-flow diagram shown below, find:

a) n if P = $1,000, A = $200, andi%=12% per year.
b) A if P = $1,000, i\% = 12\% per year, and n=5 years.

a. The value of N is approximately 10.25 years

b. The value of i is approximately 7.98%

c. The value of P is approximately $116.10

d. The value of A is approximately $304.04

a)

Formula: Use the future value formula: FV = PV * (1 + i)^n

Values: P = $1,000, A = $200, i = 12%

Solve for n: n = ln(FV / PV) / ln(1 + i) = ln($200 / $1,000) / ln(1 + 12%) ≈ 10.25 years

N ≈ 10.25 years

b)

Formula: Use the future value formula: FV = PV * (1 + i)^n

Values: P = $1,000, A = $200, N = 10 years

Solve for i: i = (FV / PV)^(1/n) - 1 = ($200 / $1,000)^(1/10) - 1 ≈ 7.98%

i ≈ 7.98%

c)

Formula: Use the present value formula: PV = FV / (1 + i)^n

Values: A = $200, i = 12%, N = 5 years

Solve for P: P = FV / (1 + i)^n = $200 / (1 + 12%)^5 ≈ $116.10

P ≈ $116.10

d)

Formula: Use the future value formula: FV = PV * (1 + i)^n

Values: P = $1,000, i = 12%, N = 5 years

Solve for A: A = FV / n = ($1,000 * (1 + 12%))^5 / 5 ≈ $304.04

A ≈ $304.04

Using the cash-flow diagram shown below, find: a) n if P = $1,000, A = $200, andi-example-1
