A. 0.40x
B. 1.20x
C. 1.40x
D. 1.60x
E. 3.20x Pick some smart number for x, let x=2 (I chose x=2 as in this case monthly shipments would be \frac{x}{2}=1). From November to February 4x=8 rakes were produced and in March business paid for storage of 8-1=7 rakes, in next month for storage of 6 and so on. So total storage cost would be: 0.1(7+6+5+4+3+2+1)=2.8 --> as x=2, then 2.8=1.4x. Answer: C.

Total Rakes produced = 4 months *x
Total Rakes sold each month March - OCt = x/2
Storage cost (3.5 + 3+ 2.5+2+1.5+1+0.5) x * 0.1
Correct Answer C

Total rakes produced 4x.
Rakes in the storage first month 3.5x
Rakes in the storage in the last month 0.5x
Average rakes in the storage 2x
Number of months rakes are in the storage 7 (There are no rakes in the storage in Oct)
so 2x * 0.1 * 8 = 1.4x
