Answer:
n=8
Step-by-step explanation:
1/2 (n + 4) = 6
n+4=12
n=8
Ummm I’m not sure but maybe try 8 x 60, and then divide your answer with 130
Yes your method is correct. But you will need to express it in percentage in the end.
So,
2 x 12 ( dozen ) = 24
24 - 18 = 6
6 / 12 = 0.5
$6 is how much you earned by selling 12 hair products.
Hence, $0.50 is how much you earned per bottle.
Transfering 0.5 into percentage would be 0.5 x 100.
Your percentage mark up would be 50 %
The standard form is ax² + bx + c = 0. We could write:
(x + 7 )(x + 8)
x²+8x+7x+56
x² + 15x + 56 → Answer
4/8 and 3/6. Both of these z= 1/2
