Step-by-step explanation:

Given:

Reward card points to be earned in order to be offered a free smoothie =75

Ken is in need of 17 more points to win a free smoothie.

∴ The current points on Ken's card must be =

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

it is x=-4
