Question and rationale: The question is: There was a big sale on cat food at the pet store. 20 people bought cat food that day. The first 8 customers bought 3 cases each. The next four customers bought 2 cases each. The last 8 customers of the day only bought 1 case each. How many cases of cat food were sold?
Step-by-step reasoning process: The first 8 customers bought 8 * 3 = 24 cases. The next 4 customers bought 4 * 2 = 8 cases. The last 8 customers bought 8 * 1 = 8. In total 24 + 8 + 8 = 40 cases were sold.

Question and rationale: The question is: Marie, the confectioner, makes 12 chocolate eggs, each weighing 10 ounces. She then packs an equal number of the eggs in 4 different gift boxes. Unfortunately, she leaves one of the boxes by the kitchen window and the afternoon sun melts everything. She tosses that box out. What is the total weight, in ounces, of the remaining chocolate eggs?
Step-by-step reasoning process: Each gift box has 12 / 4 = 3 chocolate are 12 - 3 = 9 chocolate eggs left. The remaining chocolate eggs therefore weigh 9 * 10 = 90 ounces.

Question and rationale: The question is: Pirate Rick sailed his ship to a tropical island in search of a site to bury his treasure. After finding the perfect site, it took him 4 hours to dig up 8 feet of sand under which to bury the treasure. Once the treasure was buried, he left the island. Then, a tropical storm came and washed away half of the sand from on top of the treasure. Next, a giant tsunami wave poured over the island, adding 2 feet of new sand back onto the site of his treasure. When Pirate Rick returned, how long did it take for him to dig up his treasure?
Step-by-step reasoning process: Pirate Rick digs at a rate of 8 feet of sand per 4 hours, or 8 / 4 = 2 feet per hour. Of the 8 feet of sand that were initially on top of the treasure, the storm washed 8 / 2 = 4 feet of sand away. Thus, after the storm and the tsunami, the treasure was buried beneath 8 - 4 + 2 = 6 feet of sand. Digging at a rate of 2 feet per hour, Pirate Rick could uncover his treasure in 6 / 2 = 3 hours.
