Question 2

  • Net = 5 which is less than Noise

  • Goals = 0

1 mark for the subtraction and result of the comparison

1 mark for the correct result


  • Net = 15 which is greater than Noise

  • Runs Loop one {Goals = Goals + 1, Net = Net - Noise}...

  • ...Goals = 1

1 mark for the subtraction and result of the comparison

1 mark for clearly indicating that the loop is executed once

1 mark for correct result
