the cost to a store for an mp3 player is $60. The selling price is $105 a classmate says that the markup is 175% because $105/$60= 1.75 is your classmate correct? If not, explain how to find the correct percent of markup
The mark-up on the cost is given by
[ Sales Price - Cost ] / Cost =
[ 105 - 60 ] / 60 =
