$22

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.
