Digitone$\_$Co is exploring to use air freight to transport lasers from China to Bulgaria. How much more or less they will have to pay if they shift from ocean to air transportation?

Assume the below numbers for this part $($Assume no additional cost other than the ones mentioned below$)$ :

$1.$ The total annual demand for headsets is $190000.$ The per unit cost is $600.$

$2.$ The weight of each unit of the laser is $0\mathrm{.}4$ Kg$.$

$3.$ Inventory holding cost is $1\%$ per year.

$4.$ Air rate is $5/$kg and it takes $6$ days to transport the headsets from China to Bulgaria via air.

$5.$ Ocean rate is $0\mathrm{.}9/$kg and it takes $23$ days to transport the headsets from China to Bulgaria via ocean.

$6.$ There are $365$ days in a year.

Enter the difference between the Cost of Ocean Transportation and the Cost of Air Transportation $($Ocean Cost $-$ Air Cost$)?$

Round the answer to the nearest whole number. The answer should be positive if ocean freight is greater than air freight and negative if otherwise.
