Carry out this task

  1. Create or open the Before record on the linked tool.
  2. Save the new weight, rebuild and replace the jar label.
  3. Check the saved After values before downloading the rebuilt label. Replace the older physical label.

Calculation and observed tool result

Before

Stock = 0 × 1000 + 900 = 900 g; floor(900 ÷ 250) = 3 bakes

Recorded quantity: 900 g.

After

Stock = 0 × 1000 + 650 = 650 g; floor(650 ÷ 250) = 2 bakes

Recorded quantity: 650 g.

What the result means

The replacement represents two complete bakes rather than three.

Limits of this example

The physical label does not monitor ingredient consumption.
