Answer this question:Three friends went out to watch a movie. Mitch paid for their tickets at $7 each. On the other hand, Jam paid for the 2 boxes of popcorn at $1.5 while Jay paid for the 3 cups of milk tea at $3 each. If the three of them will split the total expenses, how much should each contribute?
Three tickets cost $7 x 3 = $21. Two boxes of popcorn cost $1.5 x 2 = $3. Three cups of milk tea cost $3 x 3 = $9. The total expenses for the their tickets and food are $21 + $3 + $9 = $33. So, each of them should contribute $33 / 3 = $11.
The answer is 11.

Answer this question:John and Yasmin's dad is named Gabriel. If John has twice the number of children that her sister has and Gabriel has six grandkids, how many children does Yasmin have?
We don't know Yasmin's number of children yet, but let's represent it as Y. If John has twice the number of children Yasmin has, then John has 2 * Y = 2Y kids. If Gabriel has 6 grandkids between John's and Yasmin's children, then we can represent this as 6 = 2Y + Y. If we solve the latest equation then we learn that 6 = 3Y. Given that Y represents how many kids Yasmin has, then solving for Y we know that Y = 6 / 3 or Y = 2 kids.
The answer is 2.

Answer this question:Dale owns 4 sports cars. The red one can travel at twice the speed of the green one, but the green one can travel at 8 times the speed of the blue one. The yellow one is broken and cannot move at all. If the blue one can travel at a speed of 80 miles per hour, at what speed, in miles per hour, can the red car travel?
If the blue car can travel at 80 mph, then the green one can travel at 8 * 80 = 640 mph. If the green car can travel at 640 mph, then the red can travel at 2 * 640 = 1280 mph.
The answer is 1280.
