how would you code the following?:

In this exercise, you'll add a method and another event handler to the income tax calculator you created in Homework 3, Problem #2 Income Tax Calculatoree Taxable income: 35350 ncome tax owed: 486:7 Calculate Exdt 1. Open the TaxCalculator project and display the code for the form. 2. Code the declaration for a private method named CalculateTax that receives the income amount and returns the tax amount 3. Move the decision structure in the btnCalculate Click event handler to the CalculateTax method (if you lost points on this program in the previous homework assignment due to incorrect calculations or an inefficient decision structure, be sure to update the code to bring it into compliance). Then, declare a variable for the tax at the beginning of this method, and return the tax at the end of the method. 4. Modify the statement in the btnCalculate_Click event handler that declares the tax variable so it gets 5. Create an event handler that clears the Income Tax Owed text box if the user changes the value in the 6. Test the application to be sure it still works correctly its value by calling the CalculateTax method. Taxable Income text box
