Answer: $22
Step-by-step explanation:
First we calculate for the sale price.
We have to find how much is 60% of 50.
We do this by:

This equals 30.
We now subtract the 30 from the 50 to get our sale price.

The sale price is $20.
Now we have to add a 10% sales tax. This is done by multiply the percentage and adding 1 to it like this.

This equals 1.1
This is what we will multiply the $20 by.

The total cost is $22.
Go up 7 on the coordinate plane (up 7 on the y-axis). Go left 2 on the x-axis. Draw a dot where -2 and 7 meet. That is the point. Assuming you have a grid go up 4 and 1 to the right. Draw a point. Then go back to the first point (-2,7). Go down 4 and 1 to the left. Repeat this as many times as you want. Connect the points and draw the line.
