Step-by-step reasoning process: The checkpoints are 1 mile from the start and finish, so they are spaced along 26 - 1 - 1 = 24 miles. There are 4 equally spaced checkpoints, so the checkpoints are 24 / 4 = 6 miles apart.
[Q & A] The question is A 26-mile circular marathon has four checkpoints inside it. The first is one mile from the start line, and the last checkpoint is one mile from the finish line. The checkpoints have equal spacing between them. How many miles apart are each of the consecutive checkpoints between the start-finish line?
The answer is 6

Step-by-step reasoning process: Two times the sodas Marcy had is 22 * 2 = 44. Tina gave Marcy 44 + 12 = 56 soda. In total Marcy has 22 + 56 = 78 sodas.
[Q & A] The question is Marcy had 22 sodas in her fridge for a party. Her friend Tina came over and gave her 12 plus two times the number of sodas Marcy had before. How many sodas will Marcy have for the party?
The answer is 78

Step-by-step reasoning process: 20 pounds of fudge at $2.50 / pounds is 20 * 2.50 = $50.00. The 5 dozen truffles were sold in individual units so a dozen is equal to 12 so 5 * 12 = 60. 60 chocolate truffles, at $1.50 each sold for 60 * 1.50 = $90.00. The 3 dozen chocolate pretzels sold in individual units so a dozen is equal to 12 so 3 * 12 = 36. 36 chocolate pretzels sold for $2.00 each sold for 36 * 2 = $72.00. All total, the store made 50 + 90 + 72 = $212.00 from candy sales.
[Q & A] The question is A candy store sold 20 pounds of fudge for $2.50/pound, 5 dozen chocolate truffles for $1.50 each and 3 dozen chocolate-covered pretzels at $2.00 each. How much money did the candy store make?
The answer is 212

Step-by-step reasoning process: There are 3 families of 4 meaning there are 3 * 4 = 12 people in the vacation rental. They all use 1 oversized beach towel a day so they use 1 * 12 = 12 towels a day. They use 12 towels a day for 7 days so in one week they use 12 * 7 = 84 beach towels. The washing machine can only hold 14 towels and they have 84 towels to wash which means there are 84 / 14 = 6 loads of laundry.
[Q & A]
The question is 3 families of 4 people shared a vacation rental for 7 days. Everyone uses 1 oversized beach towel a day before getting a new one. The washing machine can hold 14 oversized beach towels per load. How many loads of laundry will it take to wash all the oversized beach towels?
The answer is 6
