Answer:
The best option for buying the Xbox One is GameStop, as the final price would be of $315.35.
Explanation:
GameStop: To obtain the price in GameStop, we must first obtain the 15% discount on the price of 350, and subtract it from the initial price. Then, we must calculate the amount of the tax and add it to the price to obtain the final price.
(350 - (350 x 0.15)) x 1.06 = $315.35
Best Buy: Instead, at Best Buy we simply add the sales price tax.
310 x 1.09 = $337.90
