What the statement means is that x^2 + kx + 2k = 0 when x = -3. That's because x + 3 will equal zero
(-3)^2 + (-3k) + 2k = 0
9 - 3k + 2k =0
9 - k = 0
9 = k
Check
=====
x^2 + 9x + 18 = 0
(x + 3)(x + 6) = 0
These are the two factors. As expected from the givens one of them is (x + 3)
Answer: She would have $315
Because there are 7 days in a week so you multiply 22.50 by 7 and you get 157.5, Then because she does it for two weeks you multiply 157.5 by 2 and you get 315
Hope this helps
