The snowiest city receive 347.7 inches on average each year.
Step-by-step explanation:
We want to find the amount of snow the snowiest city receives on average every year, "x". It is known that this city receives 113.9 more inches than the second snowiest, which receives 223.8 inches on average every year. Therefore, the expression for "x" is:

(x - 4)(x + 3) = x^2 + 3x - 4x - 12 = x^2 - x - 12
