Answer:
Final temeprature = 29 - 29 = 0c
Explanation:
The key to solving this problem is in the statement "the average temperature had fallen by 29c"
This means that the average temperature had reduced by a value of 29c from the initial value, hence we will subtract 29 from the initial temperature
Initial temperature = temperature in July = 29c
in order to find the final temperature, we will subtract 29c from the initial temperature:
Final temperature (temperature in December) = 29 - 29 = 0c
