To determine how long a gallon of milk lasts at 30 degrees Celsius, the problem requires fitting the given data points (0, 192) and (22, 42) to a mathematical function. The initial attempt involved using logarithmic equations, but it did not yield a suitable solution. Participants emphasized the need for clarity in the problem description to apply the correct mathematical approach. A suggestion was made to consider a linear equation for the data fitting. The discussion highlights the importance of providing complete information for effective problem-solving.
