The selling price of an item is ? $ 440 440. it is marked down by 20? %, but this sale price is still marked up from the cost of ? $ 320 . find the markup from cost to sale price.

10% mark up

Step-by-step explanation:

To find the sale price of an item we multiply the item's price by the percent we pay. If the item is marked down by 20% then we pay 80%.

The price is $440 (0.8)= 352. The sale price is $352.

We can create a proportion to find the markup from cost price to sale price. A proportion is n equation where two ratios are set equal to each other. We create two fractions using the prices and percents.

We begin solving by cross multiplying numerator to denominator of each fraction.

This means the price was marked up from 100% of cost price by 10%.
