The answer is most likely 20, if together, they have 26. Basically, 26 - 6 = 20.
First, you need to know what is 25 percent of 45, so you do 45 times 25 divided by 100 and you are going to get 11.25. Then you take the 45 and subtract those 11.25, which will give you 33.75 because it's saying how much was it before the sale. That's your final answer.
Use the point slope formula
plug in your numbers where 4=x1, 3=y1, 6=x2, and 7=y2
which equals 2
