Answer:
-5.14 for sam
-18.01% for dave
Explanation:
We first calculate for Sam
R = 7.3%
We have 2% increase
= 9.3%
We calculate for present value of coupon and present value at maturity using the formula for present value in the attachment
To get C
1000 x 0.073/2
= 36.5
time= 3 years x 2 times payment = 6
Ytm = rate = 9.3%/2 = 0.0465
Putting values into the formula
36.5[1-(1+0.0465)^-6/0.0465]
= 36.5(1-0.7613/0.0465)
36.5(0.2385/0.0465)
= 36.5 x 5.129
Present value of coupon = 187.20
We solve for maturity
M = 1000
T = 6 months
R = 0.0465
1000/(1+0.0465)⁶
= 1000/1.3135
Present value = 761.32
We add up the value of present value at maturity and that at coupon
761.32 + 187.20
= $948.52
Change in % = 948.52/1000 - 1
= -0.05148
= -5.14 for sam
We calculate for Dave
He has 20 years and payment is two times yearly
= 20x2 = 40
36.5 [1-(1+0.0465)^-40/0.0465]
Present value = 36.5 x 18.014
= 657.511
At maturity,
Present value = 1000/(1+0.0465)⁴⁰
= 1000/6.1598
= 162.34
We add up these present values
= 657.511+162.34 = $819.851
Change = 819.851/1000 -1
= -0.1801
= -18.01%
Answer:
Explanation:
Ordinary Annuity = Investment * PVAF(Interest, number of years)
Ordinary Annuity = $710 * PVAF(4%,5 years)
=$710 * 4.4518
=$3160.79
Answer:
C. When consumer income increases, the demand for eggs decreases.
Explanation:
Inferior goods is the type of good which demand does not increase even though the initial buyer experience an increase in purchasing power.
The reason for this is because that consumer choose to<u> purchase another product that he/she couldn't afford</u> before having an increase in income.
This 'other' product tend to be more expensive and higher in quality compared to the previous one. This is why the word 'inferior' is attached to the previous product.
From the example above, the reason why the demand for the eggs does not increase is most likely happen because the consumer choose to purchase higher quality of food. (such as a more expensive meat)
