A Television nanufacture sells 21 of TV model at$299 each, 13 of TV Model B at $549 each and 8 of TV Model C at $619 each. Find tge average price per TV Sold.

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

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
