She is incorrect as 10% of the higher marked up price is larger than 10% of the original price.
For example: If you mark up $100 by 10% you get $110.
If you mark down $110 by 10%, you will get $99, as 10% of $110 ($11) is larger than 10% of $100 ($10).
Its a little blurry and i need glasses so can u take another pic
Answer:
For finding the inflection points you'll have to put the first derivative equal to zero and solve for x. After you've done that, you can plug in the x you've just found into the original function and find also the y, so you'll find the ordered pair (x,y) of the inflection point(s).
The factors of the quadratic equation are (x+3) and (x-15).

As we can see in the quadratic equation the value of ac is -45x². therefore, we need to divide -12x into two parts such that their sum must give -12x and their product gives us -45x².
therefore, dividing -12x into -15x and 3x,

Taking common out,

Hence, the factors of the quadratic equation are (x+3) and (x-15).
