You have been tasked with writing a program for a hardware store. they sell home improvement supplies to employees, contractors and the general public. they have three different types of discounts. employees get a 10% discount, orders over $800 get a 5% discount, and contractors get a 20% discount. a customer can get only one discount but they may have an order over $800, be an employee and/or a contractor (or any combination) so you want to be sure to give them the largest discount they have earned and don’t ask them which of those they can be, because they can be all or none of them. the program will take in the total of the order, apply any discounts, apply 8% sales tax and come up with the final amount of the order. customers over 90 years old do not have to pay sales tax. they want to see the amount of the original order, the amount of any discounts, the subtotal, the amount of tax (zero for old people) and the final amount of the bill. make sure you not only get the correct answer but your code is efficiently written. don’t ask unnecessary questions (ie don't ask them if they are employee if they are a contractor, that's already the highest discount) and pay attention to how you nest your if statements.
