Let n be the first even integer. The three consecutive even integers are n, n+2, and n+4.

The sum of these three integers is given as 234:

n + (n+2) + (n+4) = 234

Combine like terms:

3n + 6 = 234

Subtract 6 from both sides:

3n = 228

Divide by 3:

n = 76

So, the three consecutive even integers are 76, 78, and 80.

We can find the discount amount by multiplying the original price by 15%: $120 * 0.15 = $18.

Now, we subtract the discount amount from the original price to find the final price: $120 - $18 = $102.

To find the average speed of the train, we divide the total distance covered by the total time taken: 100 miles / 2 hours = 50 miles per hour.

1. Fill the 3-gallon container completely.
2. Pour the 3 gallons from the 3-gallon container into the 5-gallon container.
3. Fill the 3-gallon container again.
4. Carefully pour the water from the 3-gallon container into the 5-gallon container until the 5-gallon container is full.
5. Since there was space for 2 more gallons in the 5-gallon container, you have now 1 gallon left in the 3-gallon container.
6. Empty the 5-gallon container completely.
7. Pour the remaining 1 gallon of water from the 3-gallon container into the 5-gallon container.
8. Fill the 3-gallon container completely once more.
9. Pour the entire 3 gallons from the 3-gallon container into the 5-gallon container, which already has 1 gallon in it. Now, the 5-gallon container will have exactly 4 gallons of water.

First, we find the number of people who like at least one of the ice cream flavors: 25 (both) + 15 (only chocolate) + 12 (only vanilla) = 52 people. Since some people are counted twice in this sum (those who like both flavors), we subtract the number of people who like both flavors to get the number of people who like at least one flavor: 52 - 25 = 27 people. Finally, we subtract this number from the total number of people in the group to find the number of people who like neither flavor: 60 - 27 = 33 people. However, the question asks for the number of people who like neither flavor, so we need to subtract the number of people who were counted twice (those who like both flavors): 33 - 25 = 8 people. Answer: d) 8 people.
