In November, the average temperature at the North Pole is $-8.3\degree$ Fahrenheit. In December, the average temperature at the North Pole is $7.7\degree$ Fahrenheit colder than November's average temperature. In January, the average temperature at the North Pole is $1\frac{1}{4}$
times colder than December's average temperature.
What is the average temperature, in degrees Fahrenheit, at the North Pole in January?
First, let's find the temperature in December:
December's average temperature = November's average temperature - 7.7
December's average temperature = $-8.3 - 7.7 = -16\degree$ Fahrenheit
Now, let's find the temperature in January:
January's average temperature = $\frac{5}{4}$ * December's average temperature
January's average temperature = $\frac{5}{4}$ * $-16 = -20\degree$ Fahrenheit
Therefore, the average temperature at the North Pole in January is $-20\degree$ Fahrenheit.
