given: 4.5(8-x)+36=102-2.5(3x+24)
step 1: 36-4.5x+36=102-7.5x-60
step 2: 72-4.5x=42-7.5x
step 3: 72+3x=42
step 4: 3x=-30
step 5: x=-10

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
