M6/Q11:

A certain business produced x rakes each month form 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 through 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 form November through October?

A. 0.40x

B. 1.20x

C. 1.40x

D. 1.60x

E. 3.20x

Good prob-

Nov-Feb rakes produced = 4x Storage cost= 0$

Beg of March- x/2 rakes shipped remaining = 7x/2 storage cost=0.1*7x/2

Beg of April- x/2 rakes shipped remaining = 3x storage cost=0.1*3x

Beg of May- x/2 rakes shipped remaining = 5x/2 storage cost=0.1*5x/2

Beg of June- x/2 rakes shipped remaining = 2x storage cost=0.1*2x

Beg of July- x/2 rakes shipped remaining = 3x/2 storage cost=0.1*3x/2

Beg of Aug- x/2 rakes shipped remaining = x storage cost=0.1*x

Beg of sep- x/2 rakes shipped remaining = x/2 storage cost=0.1*x/2

Beg of oct- x/2 rakes shipped remaining = 0 storage cost=0

Adding = 0.1x[7/2+3+5/2+2+3/2+1+1/2]

=0.1x[16/2+6]

=0.1x *14

=1.4x

Hence C
