Come up with a question and reasoning that would justify this answer: 30
Question and rationale: The question is: A school is planning a community outreach program. Each classroom must raise $200 for this activity. Classroom A has raised $20 from each of two families, $10 from each of eight families, and $5 from each of ten families. How much more money does Classroom A need in order to reach the goal?
Step-by-step reasoning process: Classroom A raised 2 x $20 = $40 from two families. They raised 8 x $10 = $80 from eight families. They raised 10 x $5 = $50 from ten families. Altogether, they raised $40 + $80 + $50 = $170. Therefore, they need $200 - $170 = $30 more to reach the goal.

Question and rationale:
The question is: In a jar that has 50 ants, the number of ants in the jar doubles each hour. How many ants will be in the jar after 5 hours?
Step-by-step reasoning process: After first hour, 50 * 2 = 100 ants. After the second hour, 100 * 2 = 200 ants. After the third hour, 200 * 2 = 400 ants. After the fourth hour, 400 * 2 = 800 ants. After the fifth hour, 800 * 2 = 1600 ants.
