What is h(x) = 7 + 10x + x2 written in vertex form? A:h(x) = (x - 25)^2 – 18
B:h(x) = (x - 5)^2 + 32
C:h(x) = (x + 5)^2 - 18
D:h(x) = (x + 25)^2+32

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

this doesn't make sense lol
