[Question]Johnson has a sack of potatoes. He gives Gina 69 potatoes, gives Tom twice as much potatoes as he gave Gina and gives one-third of the amount of potatoes he gave Tom to Anne. How many potatoes does he have left if the sack contains 300 potatoes?
[Answer]He gives twice 69 potatoes to Tom, which is 69 * 2 = 138 potatoes. He gives one - third of 138 potatoes to Anne, which is 138 * (1 / 3) = 46 potatoes. In total, he has given out 69 + 138 + 46 = 253 potatoes. He initially had 300 potatoes so he now has 300 - 253 = 47 potatoes left. The answer is 47.
Q: Maria has a pen and a pencil. She bought the pen for half the price of the pencil. The pencil cost her $8. How much did Maria pay for both the pen and the pencil?

Question: Simon, Gerry, and Micky want to have a race with handmade miniature rafts. Simon's raft needs 36 sticks, Gerry's raft needs two-thirds of the number of sticks that Simon needs, and Micky's raft needs 9 sticks more than Simon and Gerry's rafts combined. How many sticks do the three boys need to collect in total?
Answer: Gerry's raft needs (36 / 3) x 2 = 12 x 2 = 24 sticks. Simon and Gerry's rafts need 36 + 24 = 60 sticks. Micky's raft needs 60 + 9 = 69 sticks. The boys need to collect 60 + 69 = 129 sticks in total. The answer is 129.

[Question]The length of the straight part of a river is three times shorter than the crooked part. If the river is 80 miles long, how long is the straight part of the river?
[Answer]
Let's say the river's length in the straight part of the river is x. The total length of the river is the length of the straight part plus 3 times the length of the straight part for the crooked part, which is x + 3x = 80. The total length of the river is 4x = 80. The straight part of the river is x = 80 / 4 = 20 miles. The answer is 20.
