Profit and Loss

Kmnb147

An item sold was originally marked up by 30% of the cost price, at a discount of 58% of the selling price. What percent of the cost is the resulting profit or loss of this sale?

I used $1.00 as my cost making my sell price$1.30.
58% of sell is 0.754
1.30-0.754= 0.546 (new Sell price)
0.546-1.00= 0.454
0.454/1.00*100=45.4%

Am I even close?
