Answer: 10 months
Explanation:
It would take the Hendersons 10months to recover their cost if they decide to do it themselves over the professional service.
Here is how;
Doing it themselves would cost -
$250 - For a lawnmower
$135 - For an edger
$69 - For a hedge trimmer
$25 - For a rake
Summing these up gives $479
It would cost the Hendersons $479 to purchase equipments to carry out their monthly yard maintenance themselves.
On the other hand, if they were to hire a professional service, it would cost
• $75 for the first month and
• $45 for subsequent months
So, $45 * 9months = $405
$405 + $75 (for the initial month) = $480
Comparing the $480 for a professional to the $479 it would cost to purchase equipment and do it themselves, it would take the Hendersons 10months to recover their cost if they decide to do it themselves over the professional service.
Answer:
$594.57
Explanation:
For computing the monthly payment we need to apply the PMT formula i.e to be shown in the attachment below:
Given that,
Present value = $31,000
Future value or Face value = 0
Rate = 5.67% ÷ 12 months = 0.4725
NPER = 5 years × 12 = 60 years
The formula is shown below:
= PMT(RATE;NPER;-PV;FV;type)
The present value come in negative
So, after applying the formula, the monthly payment is $594.57
Answer:

So option (b) is correct option
Explanation:
We have given value of operation PV = $25.00
WACC, that is
= 11.50% = 0.1150
It is grow at a constant rat of 7 % so g = 0.07
We have to find the value of 
We know that value of operation is given by

So 

So option (b) is correct option
Answer:
The manufacturer should announce a guaranteed mileage of 44528 miles
Explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean
and standard deviation
, the zscore of a measure X is given by:

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:

What guaranteed mileage should the manufacturer announce
Only until the 5th percentile will have to be replaced, which is the value of X when Z has a pvalue of 0.05. So it is X when Z = -1.645.




The manufacturer should announce a guaranteed mileage of 44528 miles
Answer:
10% of exam score
Explanation:
Opportunity Cost is the cost of next best alternative, foregone (sacrifised) while making a choice.
Example : If a person has option to have an apple or an orange, & choses to have apple. The opportunity cost of having an apple is the sacrifised orange.
Given : A night before mid time exam, spent while watching movies - later lead to fall in exam grade from 70 % to 60%
The opportunity cost of movies watched, is the sacrifised grade of exam, which would have gotten, if the time would have spent in studying. The corresponding grade lost = 70% grade achievable - 60% grade achieved. Hence, the opportunity cost = 10% of exam score.
