Drew purchased a 4K Blu-ray for $18.00 and sold it to a customer on EBay for 50% more than the purchase price . The customer was charged an 8% tax when the Blu-ray was sold . What was the customers total cost for the Blu-ray ?

$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.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
