Step-by-step explanation:

How to Calculate the Total Cost of a Discounted Item with Sales Tax

To find out how much Sam will pay for the skateboard deck, we need to take a few steps involving percentages. First, let's calculate the discount on the skateboard. Since it's on sale for 15% off, we'll subtract 15% of the original price from the original price. Next, we'll find out the amount of sales tax to be added by using the tax rate given, which is 8.1%. Finally, we'll add the tax to the discounted price to get the total cost.

Here's the calculation step by step:

1. Calculate the discount amount: $33.75 × 0.15 = $5.06.
2. Subtract the discount from the original price: $33.75 - $5.06 = $28.69 (discounted price).
3. Convert the sales tax rate to a decimal and calculate the tax: $28.69 × 0.081 = $2.32.
4. Add the sales tax to the discounted price: $28.69 + $2.32 = $31.01.

Therefore, with the discount and sales tax included, Sam will pay $31.01 for the skateboard deck.
