An article in the internet says: ‘One out of 10 people are left-handed’. Simon says: ‘That means the ratio of left-handed people to right-handed people is 1:10’.Simon has made a mistake. Correct it for him.(HOTS)...

okay wait before i answer, is this for your points on a graph?

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

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5

step-by-step explanation:

i believe the answer is c.
