Answer:
B) People face trade-offs
Explanation:
A trade-off happens when you have to balance two (or three in this case) opposing situations. In economics all resources are scarce, and time is the only resource that everyone shares equally. Bob is facing opportunity costs, i.e. if he chooses to train one activity he cannot train the other.
Bob has to decide how to divide the time he can spend training. If he chooses running, he can´t swim or ride a bike. So he has to balance the time spent on each activity, probably depending on which sport he needs to train the most.
Answer:
Option C Incorrect; adjusting for price changes, his salary is less than his dad's salary
Explanation:
Adjustment to price changes = (Amount received n years ago divided by Price Index n years ago) * Price Index today
Adjustment To price changes = ($28,000 / 110.8) * 180.5 = $45613.7
The amount $28,000 is worth $45,613.7 in todays value which means that if we adjust for price changes, Dave is incorrect because his salary is worth less by an amount $613.7 from his father's salary.
Answer: 6.40%
Explanation:
Use Excel to calculate this by the formula;
= RATE(Nper,Pmt,-Pv,Fv)
Nper is number of periods = 20 * 2 = 40 semi annual periods
Pmt is the payment = $6%/2 * 1,000 = $30
Pv is the present value = $955
Fv is future value or face value = $1,000
= RATE (40,60,-955,1000)
= 3.20% * 2 (because this is a semi annual rate)
= 6.40%
Answer:
$21.67
Explanation:
Exhibit 21-3 is attached with the answer .Please find it.
Total cost of production includes the fixed cost and variable cost. Fixed Cost remains constant as $500 in the exhibit, but the variable cost changes with each production level.
Cost of producing 60 units
Variable cost = $800
Fixed cost = $500
Total cost = $800+500 = $1,300
Product cost per unit = Total cost / numbers of unit = $1,300 / 60 = $21.67
The expected return on this portfolio will be given by:
E[P]=Rf+(E[Rm]-Rf)β
Where:
Rf=Risk Free interest rate
Rm=Return on the market portfolio
β= Market Beta
The return on our portfolio will be:
E[p]=0.043+(0.128-0.043)0.013
=0.043+0.085*0.013
=0.044105
=4.4105%
