Question

The ABC Shipping Company charges the Rates listed in the following table:

Weight of the package            Rate per mile in California      Rate per mile other states

2 kg or less                                          $2.5                                                     $3.5

Over2 kg but not more than 6 kg        $3.5                                                     $5.0

Over 6 Kg but not more than 10 kg    $4.5                                                     $6.0

Over 10 Kg but not more than 30 Kg $5.0                                                     $7.5

Over 30 kg                                          $6.0                                                     $8.5

Create an application that contains two radio buttons to select California or other states, a listbox for the user to select the package’s weight class, a textbox to enter the distance it is to be shipped, and a button to calculate and display the charges on a label control when it is clicked.

Input validation: Do not accept distances of less than 5 miles or more than 3000 miles
