When you buy something for $30 and make $70 on it what is your % in profit?
When you sell something you bought for $30 at $100, you make a profit of about 233.3%. When you get such a problem, all you have to do is to take the profit, $70, divide it by the buying price, $30, and multiply the answer by 100%.
One hundred and thirty three and a third percent profit
If u sold a $30.00 item for $60.00, that's 100% profit. You would have to sell it $120.00 for a 200 % profit; so Chuck is correct.
