The markup of an MP3 player is $207.20. The markup rate is 60%. What is the selling price?

I think it's $124.32 since u take 207.20 and you multiply it buy. 6 since %60 is. 6 as a decimal

207.20 x. 40 = 82.88

207.20 - 82.88 = 124.32

So the original selling price was 124.32

Unless they were asking to find the price if the 207.20 was the value of the 60% mark up. Then you would need to find the original price from which the 207.20 came from.
