A pitcher contains 13 cups of iced tea. You drink 1.75 cups of the tea each morning and 1.5 cups of the tea each evening. When will you run out of iced tea?

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

4

step-by-step explanation:

im pretty sure it's 4 beacsue 8/2 equals 4
