[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?
[Answer]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.

[Question]Three years from now, Tully will be twice as old as Kate. How old was Tully a year ago if Kate is now 29 years old?
[Answer]Three years from now, Kate will be 29 years + 3 years = 32 years old. So by that time, Tully will be 32 years x 2 = 64 years old. This means, Tully is 64 years - 3 years = 61 years old now. Therefore, Tully was 61 years - 1 year = 60 years old last year. The answer is 60.

[Question]The movie theater sells matinee tickets for $5, evening tickets for $12, and 3D tickets for $20. If they sell 200 matinee tickets, 300 evening tickets and 100 3D tickets, how much money do they make in total?
[Answer]
First find the total revenue from the matinee tickets: $5 / ticket * 200 tickets = $1000. Then find the total revenue from the evening tickets: $12 / ticket * 300 tickets = $3600. Then find the total revenue from the 3D tickets: $20 / ticket * 100 tickets = $2000. Then add the cost of each group of tickets to find the total cost: $1000 + $3600 + $2000 = $6600. The answer is 6600.
