Question 629702

a dvd rack is marked up $18.00, which is 50% markup based on cost.  what was the cost of the dvd?


Let cost of DVD rack be R


Since after a 50% markup, the price was $18, then we can say that:


{{{1.5/1 = 18/R}}}


1.5R = 18 ----- Cross-multiplying


R, or cost of rack = {{{18/1.5}}}, or ${{{highlight_green(12)}}}
