Question

By using a function to calculate sales Tax, create a project that will produce a summary of the amounts due for Pat's Auto Repair Shop.

The Job Information form must have text boxes for the user to enter the job number, customer name, amount charged for parts. and the hours of labor.

Include labels and text boxes for Parts, Labor, Subtotal, Sales Tax, and Total Bill.

Use menus instead of Buttons.

The menus are: Calculate, Edit, Clear, Ok

The Edit Menu will have submenus for Color and Font. Use the Color Dialog and Font Dialog objects. These will affect the Display only.

The Calculate Menu finds the charges and displays them in the specified controls.

The tax rate and the hourly labor charge should be set up as named constants so that they can be easily modified if either changes., Current charges are $50 per hour for labor and 8 percent (.08) for the sales tax rate. Sales lax is charged only on parts. not on labor.

The Clear Menu clears the text boxes and resets the focus in the first text box.

The Menu OK closes the Job Information form and displays the main form. Make sure you validate all inputs except Customer Name

Do not use import System. Make the project using simple method.

frmJoblnformation Calculate Edit Clear Ok Job Number Customer Name Amount Charged Hours Of labor Parts Labor Subtotal ax Total Bill
