Program using if else ?

The question only asked you to do the if-else block but to deal with the input of the number of books as well, you need to modify the code as follows:

Console.Write("Enter number of books : ")
Dim numberOfBooks As Integer = CInt(Console.ReadLine())
Dim totalCost as Double

If numberOfBooks <= 10 Then

  totalCost = numberOfBooks * 0.5

Else 

  totalCost = 10 * 0.5 + (numberOfBooks - 10) * 0.35

End If

Console.WriteLine("Total cost is {0:C}", totalCost)

I've been using .NET since the version 1.0 beta so these questions are easy for me :)

Anyway, time now for bed here (yawn).
