susan is correct because if you multiply the unit price, which is the price for one can of soda by the amount of people going, you can get an exact count of what the price would be for the amount of people coming. on the other hand, dividing a 12-pack of soda by the number of sodas doesn’t include the amount of people who are coming which is automatically incorrect. therefore, susan is correct and john is incorrect. i hope that helps :)
