Answer:

C. 1.40x

Explanation:

1. Production:

November through February: x rakes/month* 4 months = 4x rakes.

2. Shipping and storage costs

March= 4x (initial stock) - x/2 (shipped) = 3.5 x (in stock) * 0.1$ = $0.35

April = 3.5x (stock at end of March) - x/2 (shipped) = 3x*0.1$ =  $0.30

May = 3x (stock at the end of April) - x/2 (shipped) = 2.5x*0.1$ = $0.25

June= 2.5x (stock at the end of May) - x/2 (shipped) = 2x (in stock) * $0.1 = 0.2$

July = 2x (stock at end of June) - x/2 (shipped) = 1.5x*0.1$ =  $0.15

August = 1.5x (stock at the end of July) - x/2 (shipped) = 1x*0.1$ = $0.1

Sept= 1x (stock at the end of August.) - x/2 (shipped) = 0.5 x  (in stock) * $0.1 = $0.05

October = 0.5x (stock at end of sept.) - x/2 (shipped) = 0*$0.1 =  $0

Total storage cost= $0.35x+$0.30x+$0.25x+$0.20x+$0.15x+$0.10x+$0.05x+$0x

Total storage cost = $1.40X
