You purchased two video games originally costing $54 and $42. You received a 40% discount of $21.60 on the first game and a 15% discount of $6.30 on the second. To calculate the total percent discount on the combined purchase, the discounts of $21.60 + $6.30 = $27.90 are divided by the original total price of $54 + $42 = $96, resulting in a 28% discount on the total purchase.

1. Please help with this problem on discounts and percentages.
You purchased two new video games. You received a 40% discount on game one that originally
costs $54. You received a 15% discount on game two that originally costs $42. What was the
percent discount off the total purchase (assuming no tax was involved?)
Solution
In this problem, you got a discount of 28% off the two video games. Here's how to figure this
out.
First, you find out what the discount was on each video game. For the first one, you multiply 54
by .4. That gets you $21.6 -- so you got a discount of $21.60.
Then for the second one, you multiply 42 by .15 and you get 6.3.
So you add your discounts (they come to 27.90) and you divide that by the original total price
(96.00) and you find that this is a 28% discount.
