Ans should be 1.4X

Total units produced = 4X
Total stored in March =3.5X
Total stored in April = 3.0 X and so on

Total storage cost each month is total units stored * unit cost for storage (0.1)

Add all to get 1.4 X

Pls confirm if it is correct.

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) = 1.4x

In terms of x, what was the total storage cost, in dollars, that the business for the rakes for the 12 month from November through October? a. 0.40x b. 1.20x c. 1.40x d. 1.60x e. 3.20x We know that the business didnâ€™t need to pay storage costs from November to February. So letâ€™s begin by analyzing what happened in March. Just before March, the business had 4x rakes, and at the beginning of March, they shipped out x/2 rakes; therefore, for the month of March, they had 4x - x/2 = 8x/2 - x/2 = 7x/2 rakes that required storage costs of$0.10 each.

Since they shipped out x/2 rakes at the beginning of each of the subsequent months, from April to October, the number of rakes in storage in these months are 6x/2, 5x/2, 4x/2, 3x/2, 2x/2, x/2 and 0, respectively. Including the 7x/2 rakes in March, the total number of rakes that require storage costs is:

(7x/2 + 0)/2 * 8 = 7x/2 * 4 = 14x

Since each rake cost $0.10 to store, the total storage costs are 14x * 0.1 = 1.4x dollars.
