Q: Allie, Rob, and Allyn each bought a bowl of grapes. Allie's bowl contained two more grapes than Rob's bowl. Allyn's bowl contained four more grapes than Allie's bowl. If Rob's bowl contained 25 grapes, what is the total combined number of grapes in all three bowls?
A: 83
Step-by-step reasoning process: If Allie's bowl contained two more grapes than Rob's bowl, there were 25 + 2 = 27 grapes in Allie's bowl. If Allyn's bowl contained four more grapes than Allie's bowl, there were 27 + 4 = 31 grapes in Allyn's bowl. The total combined number of grapes in all three bowls is 25 + 27 + 31 = 83 grapes.


Q: The number of soldiers on opposite sides of a war each needs 10 pounds of food every day to continue fighting effectively. However, soldiers in the second are each given 2 pounds less food than the first side. If the first side has 4000 soldiers and the other side 500 soldiers fewer than the first side, what's the total amount of pounds of food both sides are eating altogether every day?
A: 68000
Step-by-step reasoning process: The first side with 4000 soldiers is eating 4000 * 10 = 40000 pounds of food every day. Since the other side has 500 soldiers fewer than the first side, there are 4000 - 500 = 3500 soldiers on the second side. Soldiers on the second side are each given 10 - 2 = 8 pounds of food. The total amount of food the second side eats is 8 * 3500 = 28000. Altogether, the two sides eat 28000 + 40000 = 68000 pounds of food every day.


Q: While on vacation in New York, Greg went out for a lunch that cost $100. If sales tax in New York is 4% and he left a 6% tip, how much did Greg pay?
A: 110
Step-by-step reasoning process: The sales tax is worth $100 x 4 / 100 = $4. Greg left $100 x 6 / 100 = $6 tip. So, the total cost for the tax and the tip is $4 + $6 = $10. Therefore, Greg paid $100 + $10 = $110 in all.


Q: John decided to buy 10 pins for himself. They are normally $20 each but they were on sale for 15% off. How much did he spend on pins?

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

Step-by-step reasoning process: The sell reduced the price of each pin by 20 * .15 = $3. So he paid 20 - 3 = $17 per pin. So the total cost was 17 * 10 = $170.
