Answer this question:Since Jason started investing, he has earned the same amount he invested twice over in 5 months. If Jason's investment currently is worth $90, how much has he been earning per month from his investment assuming he has been earning an equal amount of returns each month?
Let's say Jason invested x amount of money. Since Jason started investing, he has earned the same amount he invested twice over in 5 months, meaning he has earned x + 2 * x = $90. This evaluates to 3x = $90. The total amount of money that Jason invested is x = $90 / 3. Jason invested x = $30. The total amount of money that Jason has earned from his investments is $90 - $30 = $60. If he earned an equal amount of money from the investment in five months, his monthly returns is 60 / 5 = $12.
The answer is 12.

Answer this question:On a farm, on average every 6 cows produce 108 liters of milk per week. In five weeks the cows produced 2160 liters of milk. How many cows are on the farm?
Per week, one cow produces 108 liters / 6 cows = 18 liters / cow. The cows produced 2160 liters of milk over 5 weeks. So we have 2160 liters / 18 liters / cow = 120 cows. Further, we have to divide 120 cows / 5 weeks = 24 cows.
The answer is 24.
