A greenskeeper wants to fertilize the eighteenth hole of a golf course, which has an area of 12,000 square feet. If the fertilizer he wants to use suggests using one bag for every 10 square yards, how many bags should he purchase?

A. 48
B. 133
C. 134
D. 266
E. 1,200



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.

Are we supposed to know the conversion between feet and yard ?
What is the source of this question ?
