Tony would divide 2/3 by 3 witch would be the same as 2/3 x 3 = 6/9 and then its 6÷3= 2 so its 2/9
The $315 cost of the couch after tax, gives the cost before tax, <em>C</em>, as the following equation;

<h3>How can the cost before tax be expressed?</h3>
The cost of the couch with tax = $315
Let, <em>t</em>, represent the tax rate, and let <em>C</em>, represent the cost before tax, we have;
315 = C + C × t
Which gives;
- The cost of the couch before tax, <em>C </em>= 315/(1 + t)
Mathematically, we have the following equation;

Step-by-step explanation:
So you know the slope is 2/3. We can write the equation y=mx+b and plug in the value we know to get y=(2/3)x+b. Since the line goes through the point, (-5,6) our equation must be true when the x and y value are plugged into the equation. We get (6)=(2/3)(-5)+b. Solving for b, we get 6=(-10/3)+b then b=28/3. This means our formula is y=(2/3)x+28/3
