The Jape Joint is a small goat-only comedy club. It has 40 small stalls that can hold up to three goats. Small stall tickets are $39.95 each. It also has 20 big stalls that can hold up to six. Tickets are $99.95 for the bigs.

Write a program to compute sales, and warn the user if stalls are oversold. Here's some I/O. Assume users don't make mistakes.

Cthulhu runs Best Bento Boxes, supplying bento boxes to goat parties, meetings, whatevs. Write a program to work out a price for an event.

Philippe Fallop, by Teagan

Philippe Fallop runs Bouc Bus, a French goat bus company. Write a program to price a bus trip, based on the number of goats, and the length of the trip.

Philippe has three buses:

• La petite carotte, seats up to 10 goats. Bus fee is €250, plus €4.80 per kilometer.
• La moyenne oignon, seats up to 40 goats. 🚌 fee is €375, plus €7.50 per kilometer.
• La grosse patate, seats up to 80 goats. 🚍 fee is €525, plus €9.20 per kilometer.
• La infini racine de yucca, seats as many goats as you want. 🚎 fee is €39,345,231, plus €1,332 per kilometer.

Here's some sample I/O:

One more. When La infini racine de yucca is used, output a warning, as seen below.

Other things:

• Assume users make no input errors. That's later in the course.
• Add comments for IPO.
• Remember the warning when selecting La infini racine de yucca.

There once was a ship that put to sea
The name of the ship
Was the Billy o' Tea
The winds blew hard
Her bow dipped down
O blow, my bully boys, blow
Huuh!

Soon may the Wellerman come
To bring us sugar and tea and rum
One day, when the tonguin' is done
We'll take our leave and go.

Make a program to take orders for the Weller Brothers, a whaling supply company in New Zealand. We'll only have the most important supplies: sugar, tea, and rum. We'll make the measurement units easier to deal with as well. Because, sanity. They used units like bushels in those days. You wouldn't believe the twisted currency system.

There are bulk discounts.

• Sugar is $1.8 per kilo for less than 10 kilos, $1.6 for less than 50, and $1.4 for 50 or more.
• Tea is $5.2 per kilo for less than 5 kilos, $5.1 for less than 10, and $4.8 for 10 or more.
• Rum is $6.7 per liter for less than 20 liters, $6.4 for less than 50, and $6.2 for 50 or more.

Output the price for each item, and the total.

Also, output "You're gonna need more rum, mate!" if the number of liters of rum is less than the sum of the number of kilos of tea and sugar. E.g., if rum is 20, tea is 12, and sugar is 10, output the message. If rum is 25, tea is 12, and sugar is 10, do not output the message.

Notes:

• Assume all user input is correct. Validation is the next part of the course.
• Users might input fractional amounts, like 3.8 kilos.
• Output the blank lines, the underline, and the prompts exactly.
• Add IPO comments.
• Hint: I had a variable named sugar_price_per_kilo. You don't have to.
