A) Cait made two errors:
- a discount is a deduction so it should be subtracted from the 100% (1.00 - 0.15 = 0.85), not added to 100% (1.00 + 0.15 = 1.15).
- she paid 6% of the discounted amount, not 6% in addition to the discounted amount.
B) Original amount × Percent remaining after discount × percent paid
= (20)(0.85)(0.06)
= $1.02

______________________________
<h3>1.) Combine x and 3x:</h3>
<em> - We combine the </em>
<em> variables because to get to the end sum of the equation, there can only be 1 variable. So to get the 1, you combine like terms. </em>
<em />
<h3>2.) Add 19 to both sides:</h3>
Cancels Out
- <em></em>
<em></em>
<em> - We do this to get 1 number left over. To do this you do the opposite of what you see. In this case we have a negative 19, so you add 19 on each side of the equals. </em>
<em />
<h3>3.) Divide both sides by 4:</h3>
÷ 
÷ 
<em> - We do this to get x alone. To do this you do the opposite of what you see. In this case we have </em>
<em> which is multiplying, so you divide by 4 on each side. </em>
<em />
So your answer is 
.

You would need to draw a graph or get some graph paper and plot those points. Then calculate the rise and the run. Rise is over the run. Then that is your slope. You get the rise by counting how many units up or down it takes to get to the point, and for the run, you count how many units across it is to get to the point. don't forget, if your units are going in a negative direction, then the number will be negative.
