Write a program that calculates the final sales price of a car, which includes additional optional packages along with sales tax. You may assume that the base price of the car is $30,000. First ask the user to choose which optional packages they want. For the purposes of this program, the user is only permitted to choose one package. Your program should display a menu of the available packages. The user should enter the package by entering the letter associated with it. W A - Basic Model (+$0.00) B- All-Wheel Drive Package ($2,500) C- Sport Package (+$3,500) D-Luxury Interior (+5,000) E- Self Driving / Self Aware (+12,000) If the user enters an invalid letter you must continue asking them to enter a letter until they enter a valid choice. Once they've entered a valid letter then ask them for the sales tax rate in their state. You should clearly indicate if they should enter, for example. 7 or 0.07 for a 7% sales tax. Finally, your program should compute the final sales price as the base The user should enter the package by entering the letter associated with it.

Once they've entered a valid letter, then ask them for the sales tax rate in their state. You should clearly indicate if they should enter, for example, 7 or 0.07 for a 7% sales tax. Finally, your program should compute the final sales price as the base price, plus the price of the chosen package, all multiplied by 1 + sales tax rate. For example, if the user chooses option D and there is a sales tax of 5%, then the final price would be $35.000 1.05 = $36.750. Your printout need not include, placeholders, but should be limited to two decimal places to indicate proper dollars/cents notation
