Question and rationale: The question is: Andrew works in a company that provides a generous vacation allotment: for every 10 days worked, you get 1 vacation day. If last year Andrew worked 300 days and took 5 days off in March and twice as many in September, how many more vacation days can Andrew still take?
Step-by-step reasoning process: If for every 10 days worked Andrew earns 1 day of vacation, then over 300 days worked he would have earned 300 / 10 = 30 days of vacation. We know he took 5 days off in March and that in September twice as much. That means in September he took 5 * 2 = 10 days off. In total, Andrew has used 5 vacation days in March and another 10 in September. Therefore, he has used 5 + 10 = 15 vacation days. If Andrew earned 30 days of vacation but has only used 15, then he can still take another 30 - 15 = 15 days off.

Question and rationale: The question is: Uncle Ben has 440 chickens on his farm. 39 are roosters and the rest are hens. 15 of his hens do not lay eggs, and the rest do. If each egg-laying hen lays 3 eggs, how many eggs will Uncle Ben have?
Step-by-step reasoning process: Uncle Ben has 440 chickens - 39 roosters = 401 hens. Uncle Ben has 401 hens - 15 that don't lay eggs = 386 hens that lay eggs. The egg - laying hens each lay 3 eggs * 386 hens = 1158 eggs.

Question and rationale: The question is: Janet is considering two options to retile her bathroom. The turquoise tiles cost $13/tile and the purple tiles cost $11/tile. If Janet needs to tile two walls that measure 5 feet by 8 feet and 7 feet by 8 feet, and each square foot of wall takes 4 tiles, how much will Janet save by buying the purple tiles instead of the turquoise ones?
Step-by-step reasoning process: First find the area of the first wall: 5 feet * 8 feet = 40 square feet. Then find the area of the second wall: 7 feet * 8 feet = 56 square feet. Then add the areas of the two walls to find the total area: 40 square feet + 56 square feet = 96 square feet. Then divide the number of square feet by the number of tiles per square foot to find the total number of tiles needed: 96 square feet * 4 tiles / square foot = 384 tiles. Then find the difference in cost per tile: $13 / tile - $11 / tile = $2 / tile. Then multiply the number of tiles by the cost difference per tile to find the total cost difference: $2 / tile * 384 tiles = $768.

Question and rationale:
The question is: A club with 30 members ordered fruit juices. Two-fifths of them ordered lemon juice. One-third of the remaining members ordered mango juice, and the rest ordered orange juice. How many members ordered orange juice?
Step-by-step reasoning process: 30 x 2 / 5 = 12 members ordered lemon juice. So, 30 - 12 = 18 members did not order lemon juice. Since 1 / 3 of the remaining ordered mango juice, then 18 x 2 / 3 = 12 members ordered mango juice. Therefore, 18 - 12 = 6 members ordered orange juice.
