Leiff goes online to buy a new video game. He finds a site that currently has a promotion of 15% off on all orders over $50. Leiff decides to buy his video game, with a price tag of $128, at this site because he knows that he will get the 15% discount when he checks out. Leiff pays 5.3% sales tax on the discounted price and pays a shipping fee of $4.75. What is the total of Leiff's online purchase?

The total price is 119

If the original price tag of the video game is $128, to get its discounted price at 15%, that means what Leiff paid for was (100-15) = 85% of the original price. So, the price of the video game then becomes (0.85 x 128) = $108.80. Since Leiff has to pay an additional 5.3% of the new price, that's (100 + 5.3) = 105.3% of the new price which is (1.053 x 108.8) = $114.57 Adding the shipping fee for the videogame, 114.57 + 4.75 = $119.32 Thus, the total price is $119.32
