Commission: 3 percent on first $2,500; 5 percent on second $2,500; 7.5 percent over $5,000. Find the total graduated commission on $5,800.

the answer is here: : )

:

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

i have no idea just need points sorry
