Question

Cody, the owner of an e-commerce site, buys emerald pendants for $400 and then sells them

on his site for $840. What percentage is the mark-up?
Write your answer using a percent sign (%).

Answer 1

The marked up percentage is 112.5%

Explanation:

The cost price of the emerald pendant = $400

The selling price of the emerald pendant = $840

Now, the Mark up Price = Selling Price - Cost Price

= $840 - $400 = $450

Also,
`\textrm{Percentage of Mark up Price}  = \frac{\textrm{the Marked up price}}{\textrm{The Cost Price}}  * 100`

=
`(450)/(400)  * 100 = 112.5`

⇒ Percentage of Mark up Price = 112.5%

Hence, the marked up percentage is 112.5%
