Question 6Case · AI-checked task
Write Sam a plan for October.
Sam asks: “Write us a plan for October that closes the gap, doesn't make the family miserable and starts a small saving habit. Something we can stick on the fridge.”
Use the dataset above (September, 5 September – 4 October 2026) and these facts: income 56,000 UAH a month (31,000 + 25,000 on the 5th); 300 UAH on the account on payday morning; spent 62,858, so the gap is 6,558. Food delivery 4,205 (10 orders), taxi 2,195 (12 rides), dinners out 4,345, coffee 1,395 (19 cups). Subscriptions 1,283 a month, of which three unused apps cost 777. The 2,300 for clothes was one child's autumn jacket. The 2,000 cash withdrawal has no record. Debt payments are 4,630 (two installments, 1,900 and 1,250, and 1,480 of credit card interest).
Write 150–250 words:
- The gap and the changes that close it, with amounts.
- Which changes are recurring and which are one-off.
- How much fun money stays, and how.
- The saving amount and when it moves.
- How Sam and his wife will see mid-month that the plan works.
