A box contains 25 packages of notebook paper. The price of the box is $56.25. Each of the packages of notebook paper cost the same amount. Which could be used to find p, the price of the package of notebook paper?

A. P -25 equals 56.25
B. P +25 equals 56.25
C. P/25 equals 56.25
D. 25P equals 56.25

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

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
