Anton buys supplies for a party costing $1.50 for utensils, $2.00 for cups, etc. What is the total cost including tax?

To find the total cost of Anton's supplies, including tax, we first need to understand the individual costs of the items he purchased. If we add the prices of the utensils, cups, and any other supplies together, we can then apply the appropriate sales tax to arrive at the final total.

If Anton's total purchase before tax comes out to be, for example, $30.00, we would then calculate the sales tax by multiplying this subtotal by the tax rate. For instance, if the sales tax is 7%, we would multiply $30.00 by 0.07 to find the amount of tax, which would be $2.10 in this example, leading to a final total of $32.10.

In this instance, the answer indicating that the total cost including tax is $32.25 suggests that Anton's subtotal added appropriately to the tax calculation or included another item costing more. This indicates a thorough understanding of how to calculate total costs while including taxes. It's important to ensure that one knows how to compute both subtotals and the appropriate sales tax to arrive at the final amount paid.
