Here is the equation:
Since 4 is next to the parentheses, you have to multiply everything in the parentheses by 4.

Now multiply 2 by 4:
Now add them together:
Your answer is <u>12x + 8</u>
$69 x 10 = $690
$96.10 x 10 = $961
$96.10 - $69 = $27.10 profit per book
$961 - $690 = $271 profit of all ten books sold
