For this case, the total amount invested is: investment = 3500 + 1000 = 4500 We must take out the percentage of what X invested. X investment = (3500/4500) * 100 = 77.78%. Therefore, X gets 77.78% of the profits: X profit = 0.7778 * 3000 = 2333.33 $ answer if the profits are distributed in proportion to the amount invested X receives 2333.33 $
