After the sales tax is included in the price of the skateboard, how much will the skateboard cost?

To determine the cost of the skateboard after including sales tax, you'll need to know the percentage of the sales tax and the original price of the skateboard. Let's assume the sales tax is 7% and the skateboard's original price is $100.

To calculate the sales tax, multiply the original price by the sales tax rate:
$100 x 0.07 = $7

Add the sales tax to the original price of the skateboard to find the total cost:
$100 + $7 = $107

Therefore, after including the sales tax, the skateboard will cost $107.
