Answer 1

Answer:

$522.00

Explanation:

• The code in Java implements two classes Order and CustomerOrder
• The Order class contains the method for the member variables orderNum, orderAmount and orderDiscounts, It also contains the method finalOrderTotal() for calculating the final order amount
• The second class CustomerOrder contains the main method and  serves as the driver class.
• The finalAmount is calculated in the method finalOrderTotal()  and the logic here substracting the discount from the orderAmount that is orderAmount - (orderAmount * orderDiscount)
• Since the orderAmount in the given example is 580 and the discount is 0.1 (i.e 58) the finalAmount will be 580 - 58 which gives 522 dollars
