(680-350)/350=.943

so you take how much you sold it for and subtract how much you paid - that equals your profit

then you divide your profit by how much you paid for it

Subtract 350 from 680. The profit is 330. Divide 330 by 350 and multiply the answer by 100. The answer will be 94%

680 - 350 = 330. This is the amount of profit that you have. Now take the 330 and divide it by 350 which is your original cost.

330/350 =.94 = 94%.
