[Question]A factory uses robots to manufacture batteries. For each battery that is made, it takes a robot 6 minutes to gather the materials for the battery and 9 minutes to create the battery. If the factory has 10 robots working on batteries at the same time, how many batteries can the robots manufacture in 5 hours?
[Answer]For each battery that a robot makes, it takes 9 + 6 = 15 minutes to create the battery. In 60 minutes, one robot can make 60 / 15 = 4 batteries per hour. If the factory uses 10 robots at the same time, then they can produce 10 * 4 = 40 batteries per hour. At a rate of 40 batteries per hour, 10 robots can produce 40 * 5 = 200 batteries in 5 hours. The answer is 200.

[Question]Tobias is a tractor salesman. His salary is based on the number of tractors he sells. For every red tractor he sells, he gets paid 10% of the sales price for each tractor. For every green tractor he sells, he gets paid 20% of the sales price for each tractor. This week, he sold 2 red tractors and 3 green tractors. The price of a single red tractor is $20,000. This week, Tobias's salary was $7000. What is the full price of a single green tractor, in dollars?
[Answer]For red tractors, 10% of the sales price is 10 / 100 * $20,000 = $2000. By selling two red tractors, he earned 2 * $2000 = $4000. Thus, of the $7000 salary he was paid this week, $7000 - $4000 = $3000 is from sales of green tractors. And since he sold three green tractors, the commission for the sale of a single green tractor is $3000 / 3 = $1000,. If $1000 is 20% of the full price, then the full price for a green tractor is (100 / 20) * $1000 = $5000. The answer is 5000.

[Question]Aaron is gathering can lids to take to the recycling center. He uses 3 equal-sized boxes of canned tomatoes and adds the lids he gets to the 14 can lids he already has. He is now taking 53 can lids to the recycling center. How many cans lids did he get from each box?
[Answer]Calculating the difference between the can lids Aaron has now and the amount that he had initially shows there were 53 – 14 = 39 can lids in the boxes of canned tomatoes. As the boxes are the same size, splitting these can lids equally shows that there were 39 / 3 = 13 can lids in each box. The answer is 13.
