Day 31

Task:

You handle order fulfillment at Larkspur Home Goods, a small online furniture store. Every order ships by one of three methods — Standard, Express or Overnight — each billed at a flat rate per kilogram: $2, $5 and $12. There are only three methods and they rarely change, so nobody wants a lookup table for them. In column D, work out each order's shipping cost directly from the method and weight.
