A​ check-processing center uses exponential smoothing to forecast the number of incoming checks each month. The number of checks

received in June was 40 ​million, while the forecast was 42 million. A smoothing constant of 0.20 is used. ​a) Using exponential smoothing and given alpha​, the forecast for the month of July​ = nothing million checks received ​(round your response to one decimal​ place). ​b) If the​ check-processing center received 45 million checks in the month of​ July, then using exponential smoothing and given alpha​, the forecast for the month of August​ = nothing million checks received ​(round your response to one decimal​ place).

Answer:

a. 41.6 million

b. 42.28 million

Explanation:

A) GIven

forecast in june = Sjune = 42 million

Checks recived in june = Xjune = 40 million

Smoothing constant = a = 0.2

So for july

Sjuly = a*Xjune + (1-a)*Sjune

=0.2*40 + (1-0.2)*42 million

=8+33.6 = 41.6 million

B) forecast in july = Sjuly = 41.6 million

Checks recived in july = Xjuly = 45 million

Smoothing constant = a = 0.2

So for August

Saugust = a*Xjuly + (1-a)*Sjuly

=0.2*45 + (1-0.2)*41.6 million

=9+33.28 = 42.28 million

<em>Note: This uses an exponential smoothing to forecast the results, but from the number of checks recived we see that it increases linearly. So we need a linear forecasting method .</em>

Elza [17]

Answer:

Phi Upsilon Nu

The total annual costs for the Alpha Ave. location with twenty persons living there is:

= $9,000.

Explanation:

a) Data and Calculations:

ANNUAL OPERATING COSTS

LOCATION   FIXED        VARIABLE                Total Costs

Alpha Ave.  $5,000      $200 per person     $9,000 ($5,000 + $200 * 20)

Beta Blvd.   $8,000       $150 per person     $11,000 ($8,000 + $150 * 20)

b)The variable cost of each location varies according to the number of persons living there and the rate incurred per person.  The fixed cost does not vary, at least, with the relevant range for either location.  When the total variable costs are computed, these are added to the fixed cost to obtain the total costs.  Then there is a comparison of the two locations to determine the location with the least total costs.
