Question: The class plans to take a field trip to the zoo. The cost to rent a school bus is $100. The cost of admission is $10 per student. The teacher is allowed in for free. If the class has a budget of $350, how many students can go on the field trip?
Answer: Step-by-step reasoning process: There is $350 - $100 = $250 available to pay for the students' admission fees. This means they can afford to bring $250 / $10 = 25 students on the trip.
So the answer is 25.

Question: Phyllis has two gardens. In the first garden, she has 20 plants and 10% are tomato plants. In the second garden, she has 15 plants and 1/3 of these plants are tomato plants. What percentage of all the plants in her two gardens are tomato plants?
Answer: Step-by-step reasoning process: The first garden has 2 tomato plants because 20 x .1 = 2. The second garden has 5 tomato plants because 15 x (1 / 3) = 5. She has 7 tomato plants in total because 2 + 5 = 7. She has 35 plants in total because 20 + 15 = 35. The proportion of tomato plants is .2 because 7 / 35 = .2. The percentage of tomato plants is 20 because .2 x 100 = 20.
So the answer is 20.

Question: Tedra is harvesting his tomatoes. He harvests 400 kg on Wednesday, and half as much on Thursday. He harvests a total of 2000 kg on Wednesday, Thursday, and Friday. How many tomatoes of the number he harvested on Friday are remaining if he gives away 700kg of them to his friends?
Answer:
Step-by-step reasoning process: Tedra harvests 1 / 2 * 400 kg = 200 kg of tomatoes on Thursday. Tedra harvests 2000 kg - 400 kg - 200 kg = 1400 kg of tomatoes on Friday. After giving away tomatoes to his friends, he is left with 1400 kg - 700 kg = 700 kg of tomatoes.
So the answer is 700.
