An item is regularly priced at 80 is on sale for 20%. there is a 3% sales tax. what is the amount of the sales tax

$1.92

Step-by-step explanation:

The regular price of an item = $80.00

The sale on the item = 20%

Price after the 20% discount = 80 -(20% × 80)

                                                = 80 - (0.20 × 80)

                                                = 80 - 16

                                                = $64

There is a rate of sales tax = 3%

The price of sales tax = 3% × 64

                                     = 0.03 × 64

                                     = $1.92

The amount of the sales tax is $1.92.
