Notes: Markups and Discounts
markup-the amount of increase, the profit made by the store
selling price-the cost of the item plus the markup
discount-the amount of the price decrease
sale price-original price minus the discount
To find the mark-up:
1. Multiply the cost times the percent of markup (convert to decimal)
$10.15 x .67 = $6.80
To find the selling price:
1. Add the markup to the cost
10.50 + 6.80 = $16.95
To find the discount:
1. Multiply the percent of discount times the selling price
30% .30 x 16.95 = 5.09
To find the sale price:
Method 1
1. Find the discount
16.95 -5.09 = $11.86
2. Subtract the discount from the selling price
16.95 -5.09 = $11.86
Method 2
1. Subtract the amount of discount from 100% 100%
2. Multiply the difference times the original price.
- 30% = 70%
16.95 x .70 = $11.86
