Leah, the owner of an e-commerce site, buys leather chairs for $420 and then sells them on her site for $638. What percentage is the mark-up?

Answer 1

638-420 = $218 markup

218/420 = about 51.9% markup

divide 218 by 420

use a calculator or long division

a 50% markup would have been 420+(1/2)(420) = $620

$638 is a little more than $630

the markup is a little more than 50%.

51.9% is a little more than 50%
