Based on the profit function in standard form: 𝑃⁡(𝑞)=−10⁢𝑞^2+300⁢𝑞−2,000 P⁡(q)=−10⁢q^2+700⁢q−12,000 P ( q ) = − 10 q 2 + 700 q − 12,000 Find the vertex of the parabola to determine at what quantity SunBright achieves maximum profit. To find the quantity q that maximizes profit, use the vertex formula: q=(−b)/(2⁢a)
