A bakery used to base the price of their produce on an individual item cost. So if a customer ordered 10 cross buns then they would be charged 10x the cost of single bun. The bakery has decided to start selling their produce prepackaged in bunches and charging the customer on a per pack basis. So if the shop sold vegemite scroll in packs of 3 and 5 and a customer ordered 8 they would get a pack of 3 and a pack of 5. The bakery currently sells the following products:

Given a customer order you are required to determine the cost and pack breakdown for each product. To save on shipping space each order should contain the minimal number of packs.

Each order has a series of lines with each line containing the number of items followed by the product code. An example input:

10 VS5
14 MB11
13 CF

A successfully passing test(s) that demonstrates the following output:

10 VS5 $17.98
  2 x 5 $8.99
14 MB11 $54.8
  1 x 8 $24.95
  3 x 2 $9.95 
13 CF $25.85
  2 x 5 $9.95
  1 x 3 $5.95
