Question

A store advertises a sale as"Get 30% off your highest prices item when you buy 2 or more items." Lee buys items with prices of 30$ abd 20$. Find the percent discount on the total purchase.

Answer 1

There was 18% discount on the total purchase.

Explanation:

Given:

Original price of the item 1 =$30

Original price of the item 2 = $20

Total Original cost of both items = $30 + $20 = $50

Now Given;

Get 30% off your highest prices item when you buy 2 or more items.

It means that when 2 or more items are bought the item with the largest value will get 30% discount.

From above we can say Lee has bought 2 items hence he is eligible for the discount and he will get the discount on item 1 which is highest cost in his items bought list.

Discount amount =
`(30)/(100)*30 =\$9`

Price of Item 1 after discount = $30 -$9 = $21

Now Total cost on both item purchase after discount will be equal to Price of Item 1 after discount plus Original price of the item 2.

framing in equation form we get;

Total cost on both item purchase after discount = $21 + $20 = $41

Now Percent discount on total purchase can be calculated by Dividing Discount amount from Total Original cost of both items and the multiply by 100;

framing in equation form we get;

Percent discount on total purchase =
`(9)/(50)* 100 =18\%`

Hence There was 18% discount on the total purchase.
