GameStop has the Xbox one advertised for 15% off the original price of $350 plus 6% sale tax online Xbox one is advertised at Best Buy for $310.00 plus 9% sales tax which is the better buy

The best option for buying the Xbox One is GameStop, as the final price would be of $315.35.

Step-by-step 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

GameStop's total will be 371.00

Best Buy's total will be 337.90

Best Buy will be the better buy

Your answer is Best Buy
