Question

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

Answer 1

Answer:

The marked up percentage is 112.5%

Step-by-step 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, $\textrm{Percentage of Mark up Price} = \frac{\textrm{the Marked up price}}{\textrm{The Cost Price}} \times 100$

= $\frac{450}{400} \times 100 = 112.5$

⇒  Percentage of Mark up Price =  112.5%

Hence, the marked up percentage is 112.5%
