For each of the following situations involving annuities, solve for the unknown. Assume that interest is compounded annually and

that all annuity amounts are received at the end of each period.

Answer:

1)$11,978

2)9%

3)15 periods

4) 6%

5) $ 78,867.70

Explanation:

<u><em>    PV       Annuity per period        rate         time   </em></u>

1.     ?                  3,000                    8%             5

2. 242,980      75,000                     ?                4

3.   161,214       20,000                    9%              ?

4. 500,000       80,518                    ?                 8

5. 250,000           ?                        10%              4

1)

C \times \frac{1-(1+r)^{-time} }{rate} = PV\\

C 3,000.00

time 5

rate 0.08

3000 \times \frac{1-(1+0.08)^{-5} }{0.08} = PV\\

PV $11,978.1301

2)

solved using excel goal seek or financial calculator

C \times \frac{1-(1+r)^{-time} }{rate} = PV\\

C 75,000.00

time 4

<em>rate 0.089998108 we set up the formula PV(A2;4,75000)</em>

<em>then we use goal seek to find which value of a2(which is the argument for rate) makes the formula equal to 242980</em>

75000 \times \frac{1-(1+0.0899981076987946)^{-4} }{0.0899981076987946} = PV\\

PV $242,980.0000

3)

C \times \frac{1-(1+r)^{-time} }{rate} = PV\\

C  $20,000.00

time n

rate 0.09

PV $161,214.0000

20000 \times \frac{1-(1+0.09)^{-n} }{0.09} = 161214\\

(1+0.09)^{-n}= 1-\frac{161214\times0.09}{20000}

(1+0.09)^{-n}= 0.27453700    

-n= \frac{log0.274537}{log(1+0.09)

-15.00004401

4)

same as (2) solved using excel

C \times \frac{1-(1+r)^{-time} }{rate} = PV\\

C 80,518.00

time 8

<em>rate 0.06000009</em>

80518 \times \frac{1-(1+0.0600000899864588)^{-8} }{0.0600000899864588} = PV\\

PV $500,000.0000

5)

PV \div \frac{1-(1+r)^{-time} }{rate} = C\\

PV 250,000

time 4

rate 0.1

250000 \div \frac{1-(1+0.1)^{-4} }{0.1} = C\\

C  $ 78,867.701

Jack's manufacture company have experienced inflation for the past three years as follows: the first year's periodic inflation r
ankoles [38]

Answer:

8.09%

Explanation:

Year          Inflation rate    1 + Inflation rate

1                     0.03                     1.03

2                     0.04                     1.04

3                         x                       1+x

Average rate  0.05                   0.05

1 + Average rate  = [(1+r1)*(1+r2)*(1+r3)]^(1/3)

1.05 = [1.03*1.04*(1*x)]^(1/3)

[1.0712*(1+x)] = (1.05)^3

[1.0712*(1+x)] = 1.157625

1 + x = 1.157625 / 1.0712

1 + x = 1.080681

x = 1.080681 - 1

x = 0.080681

x = 8.09%

Thus, the periodic Inflation rate in year 3 is 8.09%

Suppose you face a choice between a certain income of $2,000, or a 50-50 chance of income of $1,000 or $3,000. Suppose you prefe
Aleonysh [2.5K]

Solution :

The risk averse is the person who wishes to reduce the uncertainty attached to the money.

Certain income = $2000.

50-50 chance of 1000 and 3000 would income expected income of

(0.5 x 1000) +(0.5 x 3000) = 2000

Both of them gives an equal amount of income while there is uncertainty attached with the second case which makes the risk averse person disincline to follow.

Hence the statement is FALSE.

Assume that the population level in a country is X. 5 percent of the population are likely to get affected by the disease due to which it makes a population of 0.05 X population to be effected by the disease. The population level will cost  $38,000, hence making the total healthcare cost to be 1900 X.

FinnZ [79.3K]

Answer: Option (d) is correct.

According to the law of supply, it states that there is a positive relationship between the price of a commodity and the quantity supplied of a commodity. This means that as the price of a commodity increases, as a result the quantity supplied of that commodity increases.

Therefore, any change occur in the prices of a commodity will affect the quantity supplied of a commodity not supply of a commodity.
