Question 65

A parking validation system at a shopping centre uses an algorithm to determine discounted parking fees based on total spending and hours parked.

Using Figure 3, complete the table.

Figure 3

spendAmount ← USERINPUT
hoursParked ← USERINPUT
parkingFee ← 0.0
msgStandard ← "No discount applied"
msgExceeded ← "Standard rate applies"
IF hoursParked ≤ 4 AND spendAmount > 0.0 THEN
    IF spendAmount > 60.0 THEN
        parkingFee ← 1.0
        OUTPUT parkingFee
    ELSE IF spendAmount > 30.0 THEN
        parkingFee ← (hoursParked * 2) - 1.5
        OUTPUT parkingFee
    ELSE
        OUTPUT msgStandard
    ENDIF
ELSE
    OUTPUT msgExceeded
ENDIF
