Can I Still Join the Class Party?
A notice on the classroom wall says: 「クラス パーティー：6月10日（どようび）ごご2じから5じまで、3かいの きょうしつ。おかねは 500えん。6月7日（すいようび）までに たなかせんせいに はなしてください。のみものは じぶんで もってきます。おそく くる ひとは でんわを ください。でんわ：090-1234-5678」. Hana works every Saturday until 3:30. She wants to join the party, has a 500-yen coin, and can bring a drink. Today is Tuesday, June 6. She read the notice quickly and thinks, 'I can just go at 3:30 and pay at the door.' She is not sure whether her lateness is allowed and whether she must contact anyone.
1. Hana plans to arrive at 3:30. Is that allowed by the notice, and what must she do? Quote the relevant line and explain.

The notice does not forbid late arrival. It says 「おそく くる ひとは でんわを ください」, which anticipates that some people will come late and asks them to telephone. So Hana may come at 3:30, but she should call 090-1234-5678 and say she will be late.
The party runs until 5:00, so arriving at 3:30 still gives her 1.5 hours. The judgment is that 'late' is not the same as 'not allowed'; the notice handles lateness with a contact rule rather than a refusal. She should not simply appear without calling, because the organizers have asked for a phone call.
2. What is the deadline for telling Tanaka-sensei? Given today is Tuesday, June 6, can Hana wait until Friday? Explain how までに works here.

The deadline is 「6月7日（すいようび）までに」: by Wednesday, June 7, she must speak to Tanaka-sensei. までに means 'by' a time limit, and the deadline day itself is included. Since today is Tuesday, June 6, she can wait until tomorrow, Wednesday, but not until Friday.
Friday is after the deadline, so waiting until then would be too late. The practical judgment is to act today or tomorrow. Reading までに as 'until' in the sense of 'any time before the party' would be a mistake: the notice sets an earlier cutoff for the sign-up talk.
3. Hana assumes she can pay at the door and bring nothing else. Which parts of her plan are supported by the notice, and which are assumptions? What should she do?
Read the worked answer
The notice supports the amount: 「おかねは 500えん」. It does not say when or where to pay, so 'pay at the door' is Hana's assumption, not a stated rule. To be safe, she should bring the 500-yen coin and ask Tanaka-sensei when to pay.
The notice does state 「のみものは じぶんで もってきます」: each person brings their own drink. That part of her plan is supported only if she actually brings a drink; 'bring nothing else' conflicts with this line. She should bring a drink and her money, and she should call about arriving late.
