False.
The scale factor for 3 and 45 is 15.
45 / 3 = 15.
We know that 25 isn't even a whole number for the scale factor, because no number x 4 can equal 25 (whole numbers only).
25 / 3 = 6.33333
If u end up with the exact same function that you started with (that is, if f (−x) = f (x), so all of the signs are the same), then the function is even if u end up with the exact opposite of what you started with (that is, if f (−x) = −f (x), so all of the signs are switched) then the function is odd
You can just substitute $62.10 to the model of the price
P = (20 + 0.5x) + 0.15 (20 + 0.5x)
68.10 = (20 +0.5x) + 0.15(20+0.5x)
x = 68 pages
therefore the maximum number of pages she can have in her
book is 68 pages
