6 Assume you are system developer. You received a design from the system designer to develop a billingsystem for a fruit shop. By using following business-case develop the system. You can use any language for the development, but visual basic is recommended. The font color of the Total price should change according to the product color (i.e. For Apple color is Red, Mango color is yellow, Grapes color is Green).

In your application you should have payment option e.g. cash and credit card. Prior to making the payment the application must calculate the total amount based on specific order.
