The fiction c(x) = 29x + 54.5 represents the cost (in dollars) of cable for x months, including the $54.50 installation fee. how much would you have spend on cable after 6 months?

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

your answer is  

d.
