Question: Chester must deliver ten bales of hay to Farmer Brown. Farmer Brown wants Chester to supply better quality hay and double the delivery of bales of hay. If the previous hay cost $15 per bale, and the better quality one cost $18 per bale, how much more money will Farmer Brown need to meet his own new requirements?
Answer: The hay previously cost $15 per bale so 10 bales would cost $15 * 10 = $150. Double 10 bales is 10 * 2 = 20 bales. Better quality hay cost $18 per bale so 20 bales would cost $18 * 20 = $360. Farmer Brown would need $360 - $150 = $210 more. The answer is 210.
[Question]A small, old, wooden bridge can hold up to 100 kilograms at once. Mike, Megan, and Kelly are three children who decided to cross the bridge at the same time. Kelly weighs 34 kilograms, which is 15% less than Megan. Mike weighs 5 kilograms more than Megan. How much too much do the three children weigh together to cross the bridge?
[Answer]If Kelly weighs 15% less than Megan, this means Kelly's weight is 100 - 15 = 85% of Megan's weight. 85% is 0.85, so Megan weighs 34 / 0.85 = 40 kilograms. Mike weighs 5 kilograms more than Megan, so he weighs 40 + 5 = 45 kilograms. In total all three kids weigh 34 + 40 + 45 = 119 kilograms. That means to cross the bridge safely, they weigh 119 - 100 = 19 kilograms too much. The answer is 19.

Question: OpenAI runs a robotics competition that limits the weight of each robot. Each robot can be no more than twice the minimum weight and no less than 5 pounds heavier than the standard robot. The standard robot weighs 100 pounds. What is the maximum weight of a robot in the competition?
Answer: the minimum is 5 more than 100 so 100 + 5 = 105. the maximum weight of a robot is twice the minimum 105 * 2 = 210. The answer is 210.
[Question]On Saturday morning, Renata had $10 to spend. She first went and made a $4 donation in exchange for a ticket to the local charity draw. When the draw was done, she was declared the winner of the 5th prize of $90. Excited, she quickly dashed to play slots at one of the casinos in Atlantic City. Unfortunately, she lost $50 at the first slot machine, $10 at the second and $5 at the last one. Dejected, she decided to take a long walk. She soon grew thirsty and entered the first gas station she saw. She picked a $1 bottle of water and while paying for it, she bought a $1 lottery ticket. To her utter delight, she won an instant prize of $65. How much money did Renata end up having?
[Answer]After the charity ticket purchase on Saturday morning, Renata remained with 10 - 4 = 6 dollars. Adding the prize money give her 6 + 90 = 96 dollars. At the casino, she lost 50 + 10 + 5 = 65 dollars. Thus far, Renata remained with 96 - 65 = 31 dollars. The amount she spent on the bottle of water and lottery ticket is 1 + 1 = 2 dollars. This means that she remained with 31 - 2 = 29 dollars. Since she won 65 dollars, Renata’s ended up having 29 + 65 = 94 dollars. The answer is 94.
