Ask about a difference and check the reply
See this course’s project requirements
A one-page fictional bill-check record with the period and usage, charge/balance calculation, changed case and an unsent inquiry plus reply review.
Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.
What to include
- A period and meter card distinguishing cumulative readings from period kWh and actual from estimated evidence.
- A calculation table for current charges, prior balance, applied payment and the difference from the printed amount.
- A changed-input result and an unsent factual inquiry, followed by a review of the supplied fictional reply.
Review and revise
Use these criteria to check your work and choose what to improve.
- Usage is derived from the matched readings with the correct unit and stated period.
- Each charge, old balance and payment is counted once; intermediate totals and the printed-bill difference are visible.
- The changed calculation follows the supplied change and preserves the original case.
- The question uses a verified-channel plan and minimum facts; a mathematically explained charge is not described as legally valid or actually paid.

The idea in everyday life
The original record reconstructed $101 versus $105 printed. In this exercise, a fictional provider reply adds an omitted $4 service fee S4 dated 2026-10-01 to current charges. Its amount and date are supplied; the fictional reply does not supply the agreement or tariff authorizing it. Contact planning and replies remain simulated.
Separate the arithmetic, the evidence for an entry and the authority to charge it. A new documented line can explain a total without resolving every policy question.
Ask about a difference and check the reply — worked practice
Separate the arithmetic, the evidence for an entry and the authority to charge it. A new documented line can explain a total without resolving every policy question.
Write an UNSENT — FICTIONAL query. A real contact route would be located from the provider’s known official website or trusted existing bill, not an unsolicited message. In this practice, do not open a portal or send anything. Add a status column to the reply table.
Fictional reply evidence
Paste at A1.
| AItem | BSupplied evidence | CStatus to record |
|---|---|---|
| New line S4 | $4 service fee; dated 2026-10-01 | Amount and date supplied |
| Fee authority | Agreement/tariff term not provided | Unresolved question |
| Original known other charge | $4 already in the $86 current total | Do not add again |
| Original applied payment | $20 already in the $15 old balance | Do not subtract again |
Copy as plain text
1. Summarize the unexplained amount
Write the period, $101 reconstruction, $105 printed total and a request to identify the $4 difference.
You should see: An unsent factual question names one $4 difference and asks for the missing line and supporting term.
A concise question lets another person locate the issue.
2. Plan a minimal verified contact
Record the independent official-channel check and the minimum supporting facts; exclude credentials.
You should see: Channel plan: locate provider billing help independently. Share only the relevant period, entry calculations and the reference needed in a real authorized channel; never a password. No message is sent here.
A familiar logo or incoming link is not independent verification.
3. Recalculate from the supplied reply
Add S4 to current charges, then reuse the original old balance and payment.
You should see: New current charges $86+$4=$90. Amount due $90+$35−$20=$105. Difference from print: $0. Fee authorization remains unresolved.
Do not count the earlier known $4 line or $20 payment twice.
4. Assemble and label the record
Put the period card, original and changed calculations, query and reply status on one page or in one short local note.
You should see: The final record retains the original unexplained $4, the reply that explains its arithmetic and the still-open authority question. It is labeled FICTIONAL PRACTICE, not a submitted dispute, refund or resolved real account.
Keeping the source versions shows how the conclusion changed.
What to finish
An unsent query, a reply-review row and the assembled one-page fictional bill-check record.
Watch for this
Inventing a charge to force agreement, calling an explained calculation legally valid, or sending a password and unnecessary records.
How can I tell I understand it?
Propagate a changed supplied fee into the amount due and describe the remaining difference.
