Answer 1

D) No; you should multiply 2 by 12, subtract 18 and then divide by 18.

because thats what mark up is.

Answer 2

you multiply 2 by 12, subtract 18 and then divide by 12 then put it in percentage
2 x 12 ( dozen ) = 24 24 - 18 = 6 6 / 12 = 0.5
$6 is how much you earned by selling 12 hair products.
Turning 0.5 into percentage would be 0.5 x 100.

Your percentage mark up would be 50 %
