Answer: 1.72
Explanation:
Find the original price (for example 1.50 )
Get the discount percentage (for example 20% )
Calculate the savings: 20% of $1.50 = 0.3
Subtract the savings from the original price to get the sale price: $1.50 - $0.30 = 1.72
The formula for calculating the sales tax on a good or service is: selling price x sales tax rate, and when calculating the total cost of a purchase, the formula is: total sale amount = selling price + sales tax.
