14/10 = 1.4 = 140% profit
In retail your selling price is 100% and all costs and profits should be expressed as a percentage of your selling price.In your case your cost of goods sold is $10.00 which is 41.67% of $24.00 and your gross profit is $14.00 which is 58.33% of $24.00You will have to subtract your expenses from the $14.00 gross profit in order to determine your net profit before taxes.Hope this helpsJerry-the-bookkeeper
