Alloy Steel is a steel service center.

All orders are shipped to customers using:

Carrier charges $$100$ for an order

LTL shipments are charged $0\mathrm{.}01x$ as variable cost

a TL $(40,000$ pounds$)$ shipment is charged $$350($additional$)$

$x$ : number of pounds of steel shipped on the truck

Currently Alloy Steel ships orders on the day they are received. Allowing for two days in transit, this policy allows Alloy to achieve a response time of two days.

What is the cost advantage of increasing the response time to three or four days?
