You and your friend are having party. you are expecting 12 guests at this party. you would like everyone to have 4/5 of a cup of juice. how many cups of juice will you need to purchase for the party?

The number of cups needed for the party are 10.

Step-by-step explanation:

We are given that,

Total  number of guests expected = 12

The amount of juice per person = cups

So, the number of cups needed to purchase for the party is given by,

Number of cups =

i.e. Number of cups =

i.e. Number of cups = 9.6 ≈ 10 cups

Hence, the number of cups needed for the party are 10.

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

x = 12

y = 1

for the points!
