[Question]John has 25 horses. He feeds each horse twice a day and feeds them 20 pounds of food at each feeding. He buys half ton bags of food. How many of those will he have to buy in 60 days?
[Answer]He feeds each horse 2 * 20 = 40 pounds of food a day. So he uses 40 * 25 = 1000 pounds of food a day. That means in 60 days he uses 60 * 1000 = 60000 pounds of food. Each bag of food is 2000 * .5 = 1000 pounds. So he needs to buy 60000 / 1000 = 60 bags of food. The answer is 60.

[Question]Iain has 200 pennies. He realizes that 30 of his pennies are older than he is. If he wishes to get rid of these pennies and then throw out 20% of his remaining pennies, how many will he have left?
[Answer]Start with taking out the older pennies 200 pennies - 30 pennies = 170 pennies. Take the 170 pennies * .20 = 34. 170 pennies - 34 pennies = 136 pennies. The answer is 136.

[Question]Darry is a roofer and has to climb ladders multiple times a day. He climbs his full ladder, which has 11 steps, 10 times today. He also climbs his smaller ladder, which has 6 steps, 7 times today. He did not climb any steps otherwise. In total, how many times has Darry climbed a step today?
[Answer]Climbing the full ladder means Darry has climbed 11 steps * 10 times = 110 steps so far. On his smaller ladder, he has climbed 6 steps * 7 times = 42 steps. So he has climbed a step a total of 110 + 42 = 152 times today. The answer is 152.

[Question]Mark went to a store where he spent one-half of his money, and then spent $14 more. He then went to another store where he spent one-third of his starting money, and then spent $16 more. If he then had no money left, how much did he have when he entered the first store?
[Answer]
Let X be the money Mark had. Mark spent 1 / 2 * X + 14 in the first store and 1 / 3 * X + 16 in the second store. Mark has X - 1 / 2 * X - 14 - 1 / 3 * X - 16 = $0 left. Combining like terms, we get 1 / 6 * X - 30 = $0. Adding 30 to both sides and multiplying both sides by 6, we find that Mark had X = $180 when he entered the first store. The answer is 180.
