The aquarium at Aqua Wonderland is setting up a new rectangular shark tank - NSC Information Technology - Question 1 - 2016 - Paper 1

To calculate the cost of filling the tank:

1. Determine Volume in Litres: Convert the volume from cubic metres to litres:

   $$Volume_{litres} = Volume_{cubic \, metres} \times 1000$$

2. Cost Calculation: Depending on the volume, compute the cost:

   • If the volume is <= 500 litres:
     • Cost = Volume \times 0.25
   • If the volume is <= 800 litres:
     • Cost = 500 \times 0.25 + (Volume - 500) \times 0.35
   • If the volume is > 800 litres:
     • Cost = 500 \times 0.25 + 300 \times 0.35 + (Volume - 800) \times 0.45

3. Display Cost: Show the calculated cost in the respective output text box.

To determine the lifespan in years:

1. Get Input: Retrieve the lifespan in months from the text box.

2. Calculate Years and Months: Use the following calculations:

   • Years = \frac{\text{lifespan in months}}{12}
   • Months = \text{lifespan in months} \mod 12

3. Display Results: Output the result in the format: X years and Y months.

To manage the shark tank expenses effectively:

1. Input Retrieval: Extract the initial setup cost and income from the appropriate text boxes.

2. Initialize Variables: Set up a variable for the year number, starting from 1.

   • Loop through the years to calculate:
     • If setupCost > 0:
       • Yearly income = initial income
       • Display Paid off if setup complete.
       • Calculate next year's income: increase by 10%.
       • Increment year number by 1.

3. Display Results: For each year, show:

   • Year Number
   • Yearly Income
   • Adjust amounts to two decimal places.

For the activities on the opening day:

1. Random Number Generation: Generate two random numbers for each die within the range of 1-6.

2. Output Display: Show the generated numbers onto the output area.

3. Consecutiveness Check: Verify if the numbers from the two dice are consecutive. If they are:

   • Enable the appropriate radio buttons for the options.

4. User Interaction: Ensure button Question 1_5_2 is activated if the consecutive condition is met.
