If revenue for a given month is T$, revenue for m months later = T + mx
1) If December revenue is $310,000, the revenue for march = 310,000 - 9x.
M unknown and x unknown, hence NOT SUFFICIENT
2) Difference between September and June revenue is 3x
3x = 30,000
x = 10,000
M unknown, hence NOT SUFFICIENT
Combining 1 & 2,
If December is 310,000. March is 310,000 - 90,000
Thus answer = C
