Question 957520: if i pay $1.00 for something and sell it for $3.00 or $5.00 what would be the percentage of my profit?
Answer by Theo(13342)   (Show Source):
You can put this solution on YOUR website! profit = revenue - cost.
rate of profit = (revenue - cost) / cost
percent profit = rate of profit * 100.
if you buy it for 1 and sell it for 3, then your rate of profit = (3 - 1) / 1 = 2/1 and your percent profit = 200%.
if you buy it for 1 and sell it for 5, then your rate of profit = (5 - 1) / 1 = 4 / 1 and your percent profit = 400%.
if you buy it for 5 and sell it for 1, then your rate of profit = (1 - 5) / 5 = -4 / 5 and your percent profit = -400/5 = -80%.
a negative profit is the same as a loss.
a profit of -80% is a loss of 80%.
