Solve for y: 4y = 32 A. y = 4 B. y = 6 C. y = 8 D. y = 9

C

Step-by-step explanation:

4y=32

Taking 4 to the other side

y=32/4

y=8

is there answer choices?

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
