Answer: the total of Leiff’s online purchase is $119.32
Step-by-step explanation:
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. This means that the amount of discount that he gets on the video game will be
15/100× 128 = 0.15×128 = $19.2
The discounted price would be 128 - 19.2 = $108.8
Leiff pays 5.3% sales tax on the discounted price. This means that the amount of tax paid on the discounted price would be
5.3/100 × 108.8 = 5.7664
He pays a shipping fee of $4.75. The total of Leiff’s online purchase would be
108.8 + 5.7664 + 4.75 = $119.32
