Explanation / Answer

9)

' Calculate tip value

if( myValue<=50) then tip= myValue+(0.15*myValue)
else tip= myValue+(0.25*myValue)
End if

11)

Dim index As Integer = 1

Dim temp As Integer=0

Do While index <= 100

'Check for odd element
If (index /2)<>0 Then temp=temp+ index
End If

index += 1

Loop
'Display Output

Debug.WriteLine("The sum is")
Debug.WriteLine(temp)
