Question

Credit card Payment Write a program to calculate the balance and minimum payment for a credit card statement. See Fig. 5.30. The program should use the event procedure Shown m Fig. 5.31. The finance charge is 1.5% of the old balance. If the new balance is $20 or less, the minimum payment should be the entire new balance. Otherwise, the mini-mum payment should he $20 plus 10% of the amount of the new balance above $20.

I need the answer to problem 10.

Answer 1

Answer: Since the event procedure for Fig.5.3.1 is not available, the below solution is done by the assumption Vb program code: Public Class Forml Private Sub Buttonl_Click (sender As Object, e As EventArgs Handles Button1.Click Dim val As Double val = (Text Box1·Text * 1.5 / 100) + TextBox2.Text + TextBox3.Text TextBox4·Text = val If val <= 20 Then TextBox5·Text = val Else TextBox5 . Text = (val - 20) * 10 / 100 + 20 End If End Sub End Class

Sample Output: Forml Old balance credits charge Calculate New balance Minimum Payment

Form1 Old balance 200 charge 150 credits 100 Calculate New balance 253 Minimum Payment 43.3

copyable code

Public Class Form1

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click

Dim val As Double

val = (TextBox1.Text * 1.5 / 100) + TextBox2.Text + TextBox3.Text

TextBox4.Text = val

If val <= 20 Then

TextBox5.Text = val

Else

TextBox5.Text = (val - 20) * 10 / 100 + 20

End If

End Sub

End Class
