Carry out this task
- Open the linked tool and enter the displayed values.
- Keep the 40 ml remainder rather than recording a fictitious full refill.
- Choose Calculate & Save and compare the displayed result with the worked calculation.
Calculation and observed tool result
Stock = 0 × 250 + 40 = 40 ml; floor(40 ÷ 60) = 0 refills
Recorded quantity: 40 ml.
What the result means
Zero full refills does not mean zero liquid remains.
A mistake to avoid
Rounding the refill count upward would overpromise supply.
Limits of this example
Partial top-ups are not modeled as full refills.
