Wholesale price tiers and free shipping

A stationery wholesaler in Lahore quotes the unit price of a box of pens from the total quantity of the order (the whole order gets the tier price, not just the extra boxes):

  • 1 to 9 boxes: 25.00 each
  • 10 to 49 boxes: 22.50 each
  • 50 to 199 boxes: 20.00 each
  • 200 or more boxes: 17.75 each

Shipping is a flat 14.99, but it is free when the items subtotal is at least 500.00.

Task: read one integer, the number of boxes (at least 1). Print one line in the format unit=22.50 items=225.00 shipping=14.99 total=239.99 with every amount shown with 2 decimals.
