In one city, 3,546 people attended a concert but in another city, 9,238 people attended the same band's concert. estimate how many more people attended the concert in the second city by rounding to the nearest hundred and then subtracting.

take the top number and divide it by a the bottom number

step-by-step explanation:

1/2 1 divied by 2 = .5

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
