[Question]A truck can carry a maximum of 13,500 kgs of supplies. Yesterday, the truck was loaded with 100 boxes that weigh 100 kgs each. Then, it was loaded with 10 crates which weigh 60 kgs each. Today, it was loaded again with 50 sacks which weigh 50 kilograms each. How many bags weighing 40 kilograms each can we still load in the truck?
[Answer]The total weight of the boxes is 100 boxes x 100 kg / box = 10 000 kg. The total weight of the crates is 10 crates x 60 kg / crate = 600 kg. The total weight of the sacks is 50 sacks x 50 kg / sack = 2 500 kg. So, the total weight of the supplies that were already loaded is 10,000 kg + 600 kg + 2500 kg = 13,100 kg. Hence, the most weight that can still be loaded in the truck is 13,500 kg - 13,100 kg = 400 kg. This means 400 kg / 40 kg / bag = 10 bags can still be loaded in the truck. The answer is 10.
Q: John has 20% more boxes than Jules. Jules has 5 more boxes than Joseph. Joseph has 80% fewer boxes than Stan. If Stan has 100 boxes, how many boxes does John have?
A: Joseph has 100 * 0.80 = 80 less boxes than Stan. Joseph has a total of 100 - 80 = 20 boxes. Jules has 20 + 5 = 25 boxes. John has 25 * 0.20 = 5 more boxes than Jules. John has a total of 25 + 5 = 30 boxes. The answer is 30.
Question: Donna cut her pizza into 12 slices and ate half for lunch. She ate 1/3 of the remaining pizza for dinner. How many slices are left for Donna's lunch tomorrow?
Answer: Her pizza has 12 slices and she ate 1 / 2 of the pizza for lunch so that leaves 12 / 2 = 6 slices left. She eats 1 / 3 of the pizza for dinner, so she eats 1 / 3 * 6 = 2 slices. She had 6 slices and ate 2 slices, so that leaves her with 6 - 2 = 4 slices for tomorrow's lunch. The answer is 4.
[Question]One dandelion seed floated onto Mrs. Middleton's lawn, landed on good soil, and began to grow. After one month, the dandelion plant had grown to full size and developed a flower. At the end of the second month, the flower turned to 50 fluffy, white seeds, which blew onto the lawn. Only half of these seeds landed onto good soil, germinated, and began to grow, just as the first seed had done. If each of these new seedling plants produces the same number of seeds in the same amount of time as the original plant, what is the total number of seeds that these newest plants will produce in two months' time?
[Answer]Half of the 50 seeds, or 50 / 2 = 25 seeds germinated and grew. If each of the 25 plants produces 50 seeds, then a total of 25 * 50 = 1250 seeds would be produced. The answer is 1250.
Q: Angus has $20 worth of tokens less than Elsa has. If Elsa has 60 tokens and each token is worth $4, how many tokens does Angus have?
A: If each token is worth $4, then $20 worth of tokens is $20 / $4 = 5 tokens. Angus has 5 tokens less than Elsa who has 60 so Angus has 60 - 5 = 55 tokens. The answer is 55.
Question: Reginald is selling apples. He sells each apple for $1.25. He plans to use his profits to help repair his bike. His bike cost $80 and the repairs cost 25% of what his bike cost. After the repairs are paid for, 1/5 of the money he'd earned remains. How many apples did he sell?
Answer:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

The bike repairs cost $20 because 80 x .25 = 20. Call the amount he earns e. We know that e - 20 = 1 / 5e. Therefore 5e - 100 = e. Therefore, 4e = 100. Therefore, e = 25. Therefore, he sold 20 apples because 25 / 1.25 = 20. The answer is 20.
