Hi Everyone,
Welcome to the ‘Buying and Selling Game’ Contest 6 results post. This post contains a video of the ‘Buying and Selling’ Excel Model generating the selling prices for each good in each city/town.
What is the Buying and Selling Game?
For the benefit of those who have not entered this contest, here is a brief explanation of how the game works.
Participants are required to buy goods with an allocated amount of money. They are given a choice of 6 goods and all these goods are available in any of the 5 towns, cities or planets in the game. The buying prices of all goods are provided in the question.
The participants are then required to sell all of their goods on a future date (I often refer to this as Day 7, to align with number days until post payout). The selling prices for all goods in all towns, cities or planets are not provided. Instead, the question provides a minimum, maximum, and mode selling price for each good in each town, city or planet.
The participant that has the most money after selling all his or her goods is the winner.
Responses to the contest are made in the comments section of the post. If several participants end up with the same amount of money, the person who entered (commented) first will win. The format of the required entry is explained in detail in the contest itself.

Results of the contest
Table 1 contains the selling prices generated by the ‘Buying and Selling’ Game model for each kitchen appliance at each city/town.
Table 1: Selling prices of kitchen appliances
The winner of the ‘Buying and Selling’ Game contest is 
In Space Town, he bought 90 refrigerators at $550 each. He paid total of $49,500.
In Quaint Town, he sold the 90 refrigerators at $860.12 each. He received a total of $77,410.80. Therefore, he made a profit of $27,910.80 (77,410.80 – 49,500).
Highest possible profit
The strategy that would have generated the highest profit would have been to buy 625 Microwave Ovens from Titan City at $80 each and then selling them at Space Town for $125.36 (as generated by the model). This would have generated a profit of $28,350.
Table 2 contains the lowest buying prices and the highest selling prices for each kitchen appliance.
