The owner of a video game store creates the expression - 2x^2 + 24x + 174 to represent the store's weekly profit in dollars, where x represents the price of a new video game. Choose the equivalent expression that reveals the video game price that produces the highest weekly profit, and use it to determine the price.

-2 (x^2 - 12x) + 174; x = $12

-2 (x^2 - 12x - 87); x = $87

-2 (x - 6) 2 + 246; x = $246

-2 (x - 6) 2 + 246; x = $6
