Read the problem and higligts the importan information in the problem Given:Make at least php 500 profit from selling tickets at most 300 students will attend Php3 for advance &Php4 for tickets at door​

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

answer: 12x^2+6x

step-by-step explanation:

6x does not equal 24x. hope it works!

391.6 is the correct answer
