The total revenue r earned (in dollars) from producing a gift box of candles is given by r(p)=-10p^2+800p, where p is the price per unit.
a. find the revenues when the prices per box are $20, $25, and $30
b. find the unit price that will yield a maximum revenue. what is the maximum revenue? explain your results.

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
