You are at a restaurant with a group of friends and relatives, having a reunion dinner after a year of not seeing each other.

Once the meal comes to an end, its time to pay the bill. So how would you write code to split the bill?

Start with the simplest possible approach, with everyone paying the same.

Replace the following code with your own solution

xxxxxxxxxx
1
 
1
(str "Create code to calculate the bill, including what each person should pay")

Hint: Take a look at the Who am I section for ideas on how to model the bill. Also look at More Than Average for ideas on how to write code to work out how to pay the bill.

Paying what was ordered

As not everyone had eaten the same amount of food or arrived at the same time, then there was an ask for everyone to pay just what they ordered.

So create a collection to capture what each person ordered and create an itemised bill so each person knows what they should pay.

Replace the following code with your own solution

xxxxxxxxxx
1
 
1
(str "Define a detailed bill based on what each person ordered, then create an itemised bill based on each persons order")

Paying what you ate

Now it was realised that what everyone ordered is not what everyone ate. So now we need to take the order and create an itemised bill based on what everyone actually ate (lets suspend believe here a little and assume everyone knows exactly what they ate, and is honest about it).

Replace the following code with your own solution

1
(str "Define a detailed bill based on what each person ordered, then create an itemised bill based on each person actually ate")
