Worked out from Bill-of-materials arithmetic: required = per-unit quantity x units x (1 + waste); packs = ceil(required / pack size)..

How this is worked out

7 steps
  1. General craft project: 4 materials for 1 finished piece(s).
  2. Each material's requirement is multiplied by 1 and increased by 10% for waste.
  3. Material A: 100 each x 1 + waste = 110 = 5.5
  4. Material B: 2 each x 1 + waste = 2.2 = 2.64
  5. Material C: 1 each x 1 + waste = 1.1 = 3.85
  6. Material 4: 4 each x 1 + waste = 4.4 = 0.44
  7. Total material cost 12.43 = 12.43.
