Sales sample, 2026-04-01 to 2026-04-12

Source: sales-sample.csv (12 data rows, columns date, units, amount_usd). The file was read only, not modified.

Findings

Total sales: $1,250 across 12 days.
Calculation: 80 + 90 + 70 + 100 + 110 + 95 + 130 + 90 + 85 + 200 + 105 + 95 = 1250.
Check: summed once via the CSV parser and once from the raw text lines, both give 1250.
Total units: 123.
Calculation: 8 + 9 + 7 + 10 + 11 + 9 + 13 + 9 + 8 + 20 + 10 + 9 = 123. Units are a count of items, separate from dollars.
Highest day: 2026-04-10, $200 (20 units).
Lowest day: 2026-04-03, $70 (7 units).

Cautious observation

2026-04-10 ($200, 20 units) is roughly double the other days, whose amounts range from $70 to $130 with a median of $95. That single day is 16.0% of the 12-day total. The spike came from more units, not a higher price: on 2026-04-10 the amount per unit is $10, about the same as most other days (for example 2026-04-01, $80 / 8 units). With only 12 days and no context about promotions, bulk orders, or data entry, this may be a one-off and should not be read as a trend.
