1 ft^2 = 0.11 yards
so 12,000 ft^2 = 1333.33 yards
so bags required
1333.33/10 = ~134 IMO C

Area of the golf course is 12,000sq.ft. Every 10sq.yard of the golf course requires 1 bag of fertilizer.
But 1sq.yard is equivalent to 9sq.ft.
Hence total bags of fertilizer that have to be bought = 12000÷(9*10) = 133.33. We need to ceil 133.33 to 134 in order not to get short of fertilizer. Better to get some fraction of fertilizer leftover after completion of the work than to run short of it.
Answer is therefore C.
