The question is most likely asking for the cost of an item after a discount has been applied. The provided answers appear to be final prices post discount, which is derived from subtracting a discounted amount from original totals.
Step-by-step explanation:
The question is asking for a. The cost of an item after a discount. Given the list of totals and the solution examples involving sales tax, the provided answers at the bottom likely represent the final prices of items after a discount has been applied. To confirm this, we would need to know the original prices and the discount percentages, which are not provided. Usually, to calculate a discount, you subtract the discount amount from the original price. Discounts often come in the form of a percentage and therefore, you would multiply the original price by the discount rate (converted to a decimal) to find the discount amount.
For instance, if an item with a total cost of $56.75 is given a 10% discount, the calculation would be: $56.75 × 0.10 = $5.675, which is approximately $5.68 when rounded to the nearest cent. The discounted price would then be $56.75 - $5.68 = $51.07. Since this calculation method produces results similar to the answers provided, it supports the conclusion that we are looking at discounted prices.
