Solve fot = 18. The solution is t =
Which justification(s) show that your answer is reasonable?
Because
is close to 1, the value of t should be close to 18.
10
Because
9
10
< 1, the value of t should be less than 18.
Because
< 1, the value of t should be greater than 18.
10
Because io > 1, the value of t should be greater than 18.

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
