Final answer:
To determine the sale price of an item, you need to calculate the amount of discount and subtract it from the original price. For the first question, the sale price of the sweatpants is $56. For the second question, the sale price of the PlayStation 4 Pro console is $424.96. The amount of tax cannot be determined without knowing the rate of tax.
Step-by-step explanation:
To determine the sale price of an item, excluding tax, you need to calculate the amount of the discount, which is given as 30% of the original price.
For the first question, the original price of the sweatpants is $80. The amount of the discount is 30% of $80, which is $24. To find the sale price, you subtract the amount of the discount from the original price. So the sale price of the sweatpants, excluding tax, is $80 - $24 = $56.
For the second question, the original price of the PlayStation 4 Pro console is $499.95. The amount of the discount is 15% of $499.95, which is $74.99. To find the sale price, you subtract the amount of the discount from the original price. So the sale price of the console, excluding tax, is $499.95 - $74.99 = $424.96.
To determine the total cost of the console, including tax, you need to add the amount of the discount to the sale price, and then calculate the amount of tax based on the total cost.
For the second question, the discount amount is $74.99, and the sale price is $424.96. To find the total cost, you add the discount amount to the sale price: $74.99 + $424.96 = $499.95.
Finally, to determine the amount of tax, you need to know the rate of tax. Unfortunately, the rate of tax is not provided in the question. Without the rate of tax, it is not possible to determine the amount of tax.
