Answer:
18x - 22
Step-by-step explanation:
12x +<u> 2 (3x - 7)</u> - 8
underlined section is indicating that you need to multipy
so 2 mulitiplied by 3x is 6x
and 2 multiplied by 7 is 14
your new expression should look like this: 12x + (6x -14) - 8
now to simplify the expression you combine like terms, so combine the integers, and combine the X numbers.
so 12x and 6x = 18x
and (-14) and (-8) comes out to (-22)
this is the final answer:
18x - 22
I do not know the answer but my guess is all of them or at least 2 of each..?

Answer:
1.234 / 100 = 0.01234
Therefore;
0.01234 x purchase price = profit
same as
purchase price / 1.01234 = profit
formula Cost or initial Price x ( % / 100 )
and show % as a whole number ie ) 1.234 / 100 = 0.01234
= cip x 1.01234 = profit
When we divide by 100 the 1 moves two spaces to the right.
when we have to find initial price from given sale price
we deduct given percentage from 100% and use that to multiply with instead omitting the 1 if its depreciating or adding the 1 if its original price ticket.
The equation is:
12.99 + 2.10b = 21.39
Subtract 12.99 from each side to get:
2.10b = 8.4
Then divide to find the amount of bottles:
b = 4 bottles
Hope this helps!! :)
