Question
JAVA use dual arrays Your spouse's cousin's nephew's dog's trainer's best friend owns a restaurant. That person is very bad at math and recently discovered that most customers have been significantly undercharged for meals.
You have been approached to create a computer program that will accurately calculate bills for each customer.
Kids, under 5, eat free.
Teens and seniors get a 25% discount.
Also,
Food and beverage is taxed at 5%.
No tax for anything a senior or teen orders and eats.
Every person who eats at this restaurant orders exactly three items. Never greater, never fewer.
The menu is limited:
Menu Item
Price
Soup
2.50
Wings
.15 each
Burger
4.95
Chicken sandwich
5.95
Fries
1.99
Pie
2.95
Ice cream
2.99
Soft drink
1.50
Coffee
1.00
Write a program that will accurately determine a bill.
Programs must be tested. In order to test this program, use the following scenario.
A family stops at the restaurant for lunch. The family is composed of a middle aged mother and father named Bill and Nancy. They have a 2-year old child named Jesse. They are traveling with Nancy's elderly grandmother, Sarah.
Everybody decided to order a burger. Nancy and Jesse order a soft drink. Nancy and Sarah order soup. Bill orders 5 wings. Bill and Sarah order coffee. Jesse orders ice cream.
Run your program one time for each person and determine the grand total this family would owe on their bill.

Output:
