Question

1.Compute the PV of a $13,395.00 payment made in 7 years when the discount rate is 8.23%.

$8,217.29

$8.006.37

$7,700.33

$7,429.95

2)You deposit $425.00 into an account which pays 1.25% for the first two years. However, the rate of interest drops to 0.75% thereafter. About what is the value of your investment four years from today [assme annual compounding].?

$446.65

$442.25

$426.28

$20.37

3.You have $3,000.00 in an account that pays 3.2% annual interest. About how many additional dollars of interest would you earn over a two years period if you moved the money to an account earning 5.1%?

$57.00

$87.23

$118.73

$128.54

$8,217.29

$8.006.37

$7,700.33

$7,429.95

Explanation / Answer

1.Present value=$13395*Present value of discounting factor(rate%,time period)
=$13395/1.0823^7

=$13395*0.574865692

=$7700.33(Approx).

2.We use the formula:
A=P(1+r/100)^n
where
A=future value
P=present value
r=rate of interest
n=time period.

Hence

A=$425*(1+1.25/100)^2*(1+0.75/100)^2

=$425*1.040591259

=$442.25(Approx).

3.

We use the formula:
A=P(1+r/100)^n
where
A=future value
P=present value
r=rate of interest
n=time period.

For 3.2% annual interest:

A=$3000*(1.032)^2

=$3000*1.065024

=$3195.072

For 5.1% annual interest:

A=$3000*(1.051)^2

=$3000*1.104601

$3313.803

Hence excess dollars=$3313.803-$3195.072

which is equal to

=$118.73(Approx).
