This is par for the course for Comcast subscribers, who also haven't been able to watch HBO Go on the Playstation 3 since that app arrived a year ago. Comcast doesn't support HBO Go on Amazon's Fire TV devices either, and only started working with Roku last Decemberâmore than three years after the app became available.his is par for the course for Comcast subscribers, who also haven't been able to watch HBO Go on the Playstation 3 since that app arrived a year ago.

Weighted average calculation. The weighted average (x) is equal to the sum of the product of the weight (wi) times the data number (xi) divided by the sum of the weights: Example. Find the weighted average of class grades (with equal weight) 70,70,80,80,80,90: Since the weight of all grades are equal, we can calculate these grades with simple average or we can cound how many times each grade apear and use weighted average. 2Ã70,3Ã80,1Ã90.
It is helpful to separate the purchases from the sales. Goods available for sale is 415 units with a total cost of $3,394.00. If we divide $3,394.00 by 415, we get a weighted average cost of $8.18 (rounded) per unit. The rest of the calculation is very simple at this point.The company sold 245 units. We will use $8.18 as the cost of each unit, therefore the total cost of goods sold is $2.004.10.hat if we had 20 units at $100 and 10 units at $500. You might notice that the ratio of $100 units to $500 units is still the same (2:1). Letâs do the calculation to confirm that the weighted average will be the same. The total cost of all the units is $7,000 and there are 30 units.
