Key points

Size curveThe share of sales each size makes.
Allocate by curveUnits × size share: 60 × 40% = 24 mediums.
Broken sizesWhen key sizes run out, the rest stops selling.

Send each store its own curve. Stores in different areas buy different sizes.

Practice

Try each one in your head first, then open the answer.

1. Toronto's curve is S 10%, M 40%, L 35%, XL 15%. How many mediums go in a delivery of 60?
60 × 40% = 24
2. Montreal's curve is S 5%, M 35%, L 40%, XL 20%. How many larges go in a delivery of 80?
80 × 40% = 32
