Answer: $24.84
Step-by-step explanation: So if the seller sold the Blu-ray for 50% more than the original purchase price, it will equal to $27 from $18.00 - a $9.00 difference. An 8% sales tax was then charged on top of the $27.00 purchase that would total to $2.16 deduction.
$27.00 - 2.16 = $24.84 for the total cost of the Blu-ray.
