Nov - Feb = 4 mos = 4x
March - Oct = 3.5x in March, 3x in April, ..., .5x in Sep, 0x in october

0.1 / rake, so .1(sum of rakes) = .1(3.5x + 3x + ... + .5x) = .1(14x) = 1.4x, C

Ans is C 1.4x

In the first 4 months the company produces 4x rakes. For the next 8 months it ships of 4x/8 rakes per month.

If it didnt ship any it would pay storage costs of 4x * 8 * .1 = 3.2x (remember it only pays shipping costs for the last 8 months).

So the actual storage costs =
Cost to store every thing - cost to store shipped item per month
3.2x - [ .05x + .1x + .15x + .2x + .25x + .3x + .35x + .4x ]
= 1.4x
