To calculate how long it would take for the new refrigerator to pay for
itself in lower utility costs, the cost of new refrigerator will be divided by lower utility cost per
year
 
Cost of new refrigerator = $598
 
TO CALCULATE LOWER UTILITY COST PER YEAR
At a cost of only 12 cents per day
Annual cost will be 12 X 365 = 4380 Cents ($43.8)
 
Cost saved annually = Cost of old refrigerator – Cost of new
refrigerator.
Lower utility cost per year = $132 – $43.8
Lower utility cost per year = $88.2
 
How long would it take for the new refrigerator to pay for
itself in lower utility costs?
$598 ÷ $88.2
= 6.78 years

The answer is "experiment or experimental research".
Experimental research refers to the kind of quantitative research that deliberately controls at least one factors to figure out which factors casually affect different factors. Now many firms and companies are actively using this type of quantitative research on Facebook.

Answer:
Arc price elasticity of demand = -0.273
Explanation:
This problem is solved as follows:
1. Identify the data.
                    Outpatient visit       Price / visit
Tokyo           1.25 / month                  20y
Hokkaido      1.5 / month                   10y
Outpatient visits equal the quantities demanded of the service. Therefore, we can say that: 
Qt (Outpatient visits in Tokyo) = 1.25 / month 
Qh (Outpatient visits in Hokkaido) = 1.5 month.
With the following prices:
Pt (Price in Tokyo) = 20y 
Ph (Price in Hokkaido) = 10 y
2. Apply the formula to calculate arc-elasticity of demand:

We replace the data:



Final answer: -0.27275 or -0.273
