Answer:
$64
Explanation:
We know that an item which is priced at $80 has a sale of 20% and there is a 3% sales tax on it.
We are to find its price before the sales tax is added.
There is a 20% off which means the price will be (100 - 20 =) 80% of $80.
80% of $80 = 80/100 * 80 = $64
Therefore, the price of the item before the sales tax is $64.
