A laptop has a listed price of $507.95 before tax. If the sales tax rate is 6.5% , find the total cost of the laptop with sales tax included. Round your answer to the nearest cent, as necessary.
The sales tax on the laptop is 6.5% of $507.95 = $32.97
The total cost of the laptop with sales tax included is $507.95 + $32.97 = $<<507.95+32.97=540.92>>540.92. Answer: \boxed{540.92}.
