Juan reads a book with 368 pages. savannah reads a book with 172 fewer pages than juan's book. how many pages are in the book savannah reads?

There are 196 pages in Savannah's book .

Step-by-step explanation:

Given : Juan reads a book with 368 pages.

Savannah reads a book with 172 fewer (less) pages than Juan's book.

Then, by using SUBTRACTION OPERATION, we have

The number of pages in Savannah's book =

Hence, there are 196 pages in Savannah's book .

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
