Reasoning & answer: CoT: The gummy bears cost 10 * 2 = $20. The chocolate chips cost 5 * 20 = $100. The total cost for these two is 100 + 20 = $120. The chocolate bars in total cost 150 - 120 = $30. A single chocolate bar costs 30 / 10 = $3.
The answer: 3
Question: Jessica is having a sweet tooth and bought 10 chocolate bars, 10 packs of gummy bears, and 20 bags of chocolate chips. Her total rang up to $150. If the cost of a pack of gummy bears is $2 and a bag of chocolate chips costs $5, how much does 1 chocolate bar cost?

Question: John goes to the market with €100. He buys a roast for €17 and vegetables for €11. How much money does he have left?

Reasoning & answer: CoT: Since Venice has 25 more theme parks than Jamestown, there are 20 + 25 = 45 theme parks in Venice. Together, Venice and Jamestown have 45 + 20 = 65 theme parks. With 50 more theme parks than Jamestown, Marina Del Ray has 50 + 20 = 70 theme parks. The total number of theme parks in the three towns is 70 + 65 = 135.
The answer: 135
Question: Jamestown has 20 theme parks. If Venice has 25 more theme parks than Jamestown, and Marina Del Ray has 50 more theme parks than Jamestown, calculate the number of theme parks present in the three towns.

Reasoning & answer: CoT: If there are 600 boys at the event, and the difference between boys and girls is 400, there are 600 + 400 = 1000 girls. The total number of boys and girls at the event is 1000 + 600 = 1600. 60% of the total number of boys and girls at the event is 60 / 100 * 1600 = 960.
The answer: 960
