EDIT: I'm sorry. Just realized this question was discussed here https://www.beatthegmat.com/interesting- ... tml#724362
A certain business produced x rakes each month from November through February and shipped x/2 rakes at the beginning of each month from March to October. The business paid no storage costs for the rakes from November through February, but it paid storage costs if $0.10 per rake each month from March to October for the rakes that had not been shipped. In terms of x, what was the total storage cost, in dollars, that the business paid for the rakes for the 12 months from November through October?
A) $0.40x
B) $1.20x
C) $1.40x
D) $1.60x
E) $3.20x
OA: C
I was able to solve this by adding up the sum of 10% of each part monthly. Can someone help me to find a quicker way to solve this?
Thanks,

In the 4 months leading up to March, the company PRODUCES 4x rakes (4 months at x/month = 4x)A certain business produced x rakes each month from November through February and shipped x/2 rakes at the beginning of each month from March through October. The business paid no storage costs for the rakes from November to February, but it paid storage costs of 0.10$ per rake each month from March through October for the rakes that had not been shipped. In terms of x, what was the total storage cost, in dollars, that the business paid for the rakes for the 12 months from November through October?
A) 0.40x
B) 1.20x
C) 1.40x
D) 1.60x
E) 3.20x
On March 1, x/2 rakes are SHIPPED, leaving 3.5x rakes for which the company must pay storage fees.
On April 1, x/2 rakes are SHIPPED, leaving 3x rakes for which the company must pay storage fees.
On May 1, x/2 rakes are SHIPPED, leaving 2.5x rakes for which the company must pay storage fees.
etc... (this pattern continues until no rakes remain).
The total NUMBER of rakes (for which storage fees are paid) = 3.5x + 3x + 2.5x . . . + 1x + 0.5x
= 14x
The charge is $0.1/rake, so the total FEE = (0.1)(14x) = [spoiler]1.4x = C[/spoiler]
Cheers,
