Final answer:
To find the total cost of the apple pies, we need to consider the discount and sales tax. The discounted price per pie is $3.20 and the sales tax per pie is approximately $0.19. Therefore, the total cost per pie is $3.39.
Step-by-step explanation:
To find the total cost of the apple pies, we need to consider the discount and sales tax. First, let's calculate the discounted price of each pie. A 20% discount on $4 is $4 * 0.20 = $0.80. So the discounted price per pie is $4 - $0.80 = $3.20.
Next, let's calculate the sales tax. A 6% sales tax on $3.20 is $3.20 * 0.06 = $0.192. So the sales tax per pie is approximately $0.19.
Finally, to find the total cost, we add the discounted price and the sales tax. The total cost per pie is $3.20 + $0.19 = $3.39.
