Answer:
a-1 Present value = 6,177.39
a2- Present Value =6,227.79
a3- Choose the payment stream with the highest present value = a2
b1- Present Value=3,353.98
b2-Present Value=2,805.28
b3-Choose the payment stream with the highest present value = b1
Explanation:
a-1 describes an ordinary annuity whose present value is calculated as follows:
![Present value =PMT*\frac{[1-(1+i)^-^n]}{i}](https://tex.z-dn.net/?f=%20Present%20value%20%3DPMT%2A%5Cfrac%7B%5B1-%281%2Bi%29%5E-%5En%5D%7D%7Bi%7D)
where PMT=$800; i= 5%, n= 10
![Present value =800*\frac{[1-(1+0.05)^-^1^0]}{0.05}](https://tex.z-dn.net/?f=%20Present%20value%20%3D800%2A%5Cfrac%7B%5B1-%281%2B0.05%29%5E-%5E1%5E0%5D%7D%7B0.05%7D)
= 6,177.39
a2- ![Present value =600*\frac{[1-(1+0.05)^-^1^5]}{0.05}](https://tex.z-dn.net/?f=Present%20value%20%3D600%2A%5Cfrac%7B%5B1-%281%2B0.05%29%5E-%5E1%5E5%5D%7D%7B0.05%7D)
= 6,227.79
a3- If I were receiving these payments annually, I would prefer the payment stream with the highest present value ie a2 -Annual payment of $600 for 15 years at 5% interest.
b1- ![Present value =800*\frac{[1-(1+0.20)^-^1^0]}{0.20}](https://tex.z-dn.net/?f=Present%20value%20%3D800%2A%5Cfrac%7B%5B1-%281%2B0.20%29%5E-%5E1%5E0%5D%7D%7B0.20%7D)
= 3,353.98
b2-![Present value =600*\frac{[1-(1+0.20)^-^1^5]}{0.20}](https://tex.z-dn.net/?f=Present%20value%20%3D600%2A%5Cfrac%7B%5B1-%281%2B0.20%29%5E-%5E1%5E5%5D%7D%7B0.20%7D)
=2,805.28
b3- f I were receiving these payments annually, I would prefer the payment stream with the highest present value ie b1- Annual payment of $800 for 10 years at 20% interest.
Answer:
Kindly check explanation
Explanation:
Given the data:
140 82 265 168 90 114 172 230 142 86 125 235 212 171 149 156 162 118 139 149 132 105 162 126 216 195 127 161 135 172 220 229 129 87 128 126
175 127 149 126 121 118 172 126
70 - 104
105 - 139
140 - 174
175 - 209
210 - 244
245 - 279
B.) Using a class interval of 30; with lower limit of 80;
Class interval ___frequency __R/frequency
80 - 110 ________ 5 ________ 11.4
111 - 141 ________ 17 ________38.6
142 - 172 _______13 ________29.5
173 - 203 ______ 2 _________0.05
204 - 234 ______5 _________11.4
235 - 265 ______2 _________0.05
From the frequency table above, we can observe that the initial amount a beginner expends on supplies is largely between $111 to $172 ; with 38.6% of the collected samples spending between $111 and $141 and 29.5% spending between $142 and $172.
Answer: Commodity, because it was backed by a valuable good.
Explanation:
In the Prisoner of War camp in question, the prisoners had come up with a trade system where they used paper money that was backed by cigarettes. This made that paper money a commodity because it was backed by a valuable good in the camp which was cigarettes.
Commodity money such as this one used to be widely used by nations as their currency would be backed by valuable metals such as gold and silver.
