To find the actual cost of the headphones including the sales tax, you need to add the sales tax to the original price of the headphones.

Step 1: Calculate the sales tax amount
The sales tax is 7% of the original price. To find this, multiply 7% (or 0.07) by the original price of $82.00.
Sales tax = 0.07 * $82.00

Step 2: Add the sales tax amount to the original price
To find the actual cost, add the sales tax amount to the original price.
Actual cost = $82.00 + sales tax

Now, let's calculate the sales tax and the actual cost:
Sales tax = 0.07 * $82.00 = $5.74
Actual cost = $82.00 + $5.74 = $87.74

Therefore, the actual cost of the headphones, including the 7% sales tax, is $87.74.
