To calculate the total cost of the board game including sales tax, we need to add the sales tax amount to the cost of the game.
First, we need to calculate the sales tax amount. Multiply the cost of the game ($15.50) by the sales tax rate (6.50% expressed as a decimal):
Sales tax amount = 15.50 * 0.065 = $1.0075
Next, we add the sales tax amount to the cost of the game to get the total cost:
Total cost = 15.50 + 1.0075 = $16.5075
Rounding appropriately, the total cost of the board game including sales tax in Kansas is approximately $16.51.
