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.
