Amira sells balloon animals. She uses the same number of balloons for each animal she makes.
The table compares the number of balloon animals sold and the remaining number of balloons on a
certain day.
How many balloon animals at most can Amira sell?

probability for j is 1/4

while

a is 1/6

step-by-step explanation:

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
