Homework Answers

Answer #1

As per rules I am answering the first 4 subparts of the question

1: Using financial calculator

Input: PV =-100

I/Y = 6

FV = 200

Solve for N = 11.9

This is number of semiannual periods.

Hence Number of years = 11.9*2 = 23.79 years

2: The answer depends upon the number of years he lives. Suppose he lives for 20 years after retirement.

Using financial calculator

Input: PV = -250000

PMT = 30000

N = 20

Solve for I/Y = 10.32

Hence rate = 10.32%

3: Using financial calculator

Input: PV = -2000

I/Y = 12/4 = 3

N = 2*4 = 8

Solve for Fv = 2,533.54

4: Using financial calculator

Input: PV =-2000

I/Y = 7

FV = 2360

Solve for N= 2.45

It will take 2.45 years.

5:

Using financial calculator

Input: PV = -3000

FV= 4000

N = 1

Solve for I/Y = 33.33

Rate = 33.33%
