My Answer:
Private Sub btnComputeGrowthMoney_Click(sender As Object, e As EventArgs) Handles btnComputeGrowthMoney.Click
'Display simple interest and compound interest from 1 to 9
Dim simple, compound, principal As Decimal
Dim rate As Double
Dim year As Integer
lstInterest.Items.Clear()
principal = 1000
rate = 0.05
simple = principal * (1 + rate * year)
compound = principal * (1 + rate) ^ year
For year = 1 To 9
lstInterest.Items.Add("YEAR" & " " & "SIMPLE INTEREST" & " " & "COMPOUND INTEREST")
lstInterest.Items.Add(year & " " & simple.ToString("N") & " " & compound.ToString("C"))
Next
End Sub
