Luisa needs to pay $8.56 including sales tax.
Step-by-step explanation:
Price of piece of sandwich = $8
Sales tax = 7%
Amount of sales tax = 7% of price of sandwich
Amount of sales tax = [tex]\frac{7}{100}*8[/tex]
Amount of sales tax = [tex]\frac{56}{100} = \$0.56[/tex]
Total price to pay = Price of piece of sandwich + amount of sales tax
Total price to pay = [tex]8+0.56 = \$8.56[/tex]
