Answer:
no
the marginal benefit of working overtime in terms of income is less than the marginal cost of working overtime
Explanation:
According to the marginal cost principle, i would be willing to work if marginal benefit exceeds marginal cost
Marginal cost = 32 + 6.5 + 12 + 55 = 105.50
Marginal benefit = 99
the marginal benefit of working overtime in terms of income is less than the marginal cost of working overtime. So, i won't work overtime
Answer:
The rate of return on the investment if the price fall by 7% next year is -22% which is shown below.
The price of Telecom would have to fall by $71.43($250-$178.57), before a margin call could be placed.
Lastly,if the price fall immediately,the margin price would $178.57 as shown below
Explanation:
Total shares bought=$40000/$250=160 shares
Interest on amount borrowed=8%*$20000=$1600
When the price falls by 7% the new price =$250(1-0.07)=$232.50
Hence rate of return=(New price*number of shares-Interest-total investment)/initial investor's funds
=($232.50*160-$40000-$1600)/$20000=-22%
Initial margin=investor's money/total investment=$20000/$40000=50%
maintenance margin=30%
Margin call price=Current price x (1- initial margin)/ (1- maintenance margin)
=$250*(1-0.5)/(1-0.3)
=$178.57
I think that's false, these questions are weird. they're vague and subjective, not objective. In some places, being critical is important, in others it's important to forgive yourself and just go with the flow. Hope this helps, Robanddawn !
Given:
Future value, F=60508.29
Monthly payment, A = 165
Compounding period = month
Number of periods, n = 12*12=144
interest per period = i [ to be found ]
We have the relationship
F=A((1+i)^n-1)/i
but there is no explicit formula for i for given F, A and n.
We need to solve a non-linear equation for the value of i, the monthly interest rate.
One of the ways is to solve it by fixed iteration, i.e.
1. using the given relation, express i in terms of other parameters.
2. select an initial value of i
3. evaluate i according the equation in step 1 until the value is stable.
Here we will use the relationship to express
i=((60508.29*i)/165+1)^(1/144)-1 [ notice that i is on both sides of = sign ]
using an initial value of i=0.01 (about 1% per month).
Successively, we get
i=((60508.29*0.01)/165+1)^(1/144)-1=0.01075571
i=((60508.29*0.01075571)/165+1)^(1/144)-1=0.011160681, similarly
i=0.0113685
i=0.0114728
i=0.0115246
i=0.0115502
i=0.0115628
i=0.0115690
i=0.0115720
Assuming the above has stablilized, and the APR is 12 time the above value, namely
Annual percentage rate = 0.01157205998210142*12=0.13886=13.89%
