A liquid bottling system uses the algorithm shown below to determine how many standard bottles can be filled from a given starting volume of liquid.
constant BATCH_SIZE ← 150
constant RESERVE ← 50
OUTPUT 'Enter total volume of liquid in ml'
liquidVolume ← USERINPUT
stepReduction ← BATCH_SIZE + RESERVE
bottlesFilled ← 0
REPEAT
liquidVolume ← liquidVolume - stepReduction
bottlesFilled ← bottlesFilled + 1
UNTIL liquidVolume ≤ 0
Complete the trace table below for when the user enters the value 500 at the prompt.
| liquidVolume | stepReduction | bottlesFilled |
|---|---|---|
| 500 | ||
