Acafiteria sells 30 drinks evrey 15 min predict whether at the rate the cafiteria will ell at least 90 drinks evrey hour

If it stays at the same pattern then it would be 120 drinks per hour because 15 only goes into 60, 4 times so you would times 30 by 4

Plz give brainliest

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
