Answer:
Step-by-step explanation:
The formula for determining average is expressed as
Average = the total cost of the televisions/ the sum of the televisions
Total number of model A television that was sold is 21
Total cost of 21 televisions = 299 × 21 = $8671
Total number of model B television that was sold is 13
Total cost of 13 televisions = 549 × 13 = $7137
Total number of model C television that was sold is 6
Total cost of 6 televisions = 619 × 6 = $3714
Total number televisions sold is 21 + 13 + 6 = 40
Total cost of the televisions is 8671 + 7137 + 3714 = 19522
Therefore, the average price per TV Sold is
19522/40 = $488.05 per television
