Answer: Divide the sale price by the percentage amount that was paid.
Step-by-step explanation:
If a book is on sale for $6.30 with a 30% discount it means that you paid 70% of the original cost. In order to determine what the original cost was you can divide the sale price by the percentage that was paid:
$6.30 / .7 = $9.00, which is the original price of the book.
You can then double check your work - $9 x 70% = $6.30.

Step-by-step explanation:
So here are the answers to the given questions above:
1. Since the equation is already given, what we are going to do is to solve for x first.
<span>x + (2x – 10) + 1/2 (2x – 10) = 145
x + (2x -10) + x - 5 = 145
x + 2x + x - 10 - 5 = 145
4x = 145 +10 + 5
4x = 160 <<divide both sides by 4 and we get
x = 40.
Therefore, the amount of white paint is 40ml.
The amount of blue paint is 70ml and the green paint is 35ml.
So the difference between the a</span><span>mounts of white paint and blue paint Vivian combined is 30ml.
2. T</span>he equation of the line that passes through the points (-2, 1) and (1, 10) would be: <span>3x - y = -7, the last option. In order to check, just plug in the given ordered pairs.</span>
