Question 118969
What seems to be missing information is that there is 1 shipper per
shift, but I'm taking that for granted, since that's usually the case.
The logistics manager wants to know things on a weekly basis.
(1) First he wants to know (grams of chocolate shipped / week)
Let {{{C}}} = grams of chocolate shipped per week
Let {{{K}}} = kilograms of chocolate per carton
Let {{{S}}} = number of shippers shipping chocolate per week
C g/wk = (14 shifts/wk)x(1 shipper/shift)x(6 cartons/shipper)x(24 bars/carton)x
(80 g/bar)
You'll notice that, as far as units go, on the right side, "shifts" is
on the top and bottom and therefore cancels. The same is true for "shipper",
"carton", and "bar". I am left with g/wk = g/wk as I should.
Calculating:
{{{C = 14*1*6*24*80}}}g/wk
{{{C = 161280}}}g/wk answer
or
mass in kg = (161280 g/wk)x(1 kg / 1000g)
{{{C[2] = 161.280}}}kg
----------------------- 
(2) S shippers/wk = (1 shipper/shift)x(14 shifts/wk)
{{{S = 1*14}}}
{{{S = 14}}}shippers answer
-----------------------
(3) kg / carton = (1 kg / 1000 g)x(24 bars/carton)x(80 g/bar)
{{{K = (1/1000)*24*80}}}
{{{K = 1.92}}}kg/carton answer
Notice that, with just units, "g" and "bars" cancel on the right side
and I'm left with kg/carton = kg/carton.
