I'm passing the argument in a suitable array-format for convenience and brevity:
promo←{(⊂'')~⍨(⊂⍵){(⍺[1]≤+/⍺[2]≤2⊃⍵)/1⊃⍵}¨3⊃⍵}
promo 5 20(('John Doe'(22 30 11 17 15 15 52 27 12))('Jane Doe'(5 17 30 33 40 22 26 10 11 45))) ┌────────┐ │Jane Doe│ └────────┘ promo 2 50 (('Joey Bonzo'(22 67 53 29))('Jennifer Bonzo'(51 19))) ┌──────────┐ │Joey Bonzo│ └──────────┘ promo 3 15 (('Natsumi Sakamoto'(15 15 14))('Gorou Hironaka'(15 15 15))('Shinju Tanabe'(120 40))) ┌──────────────┐ │Gorou Hironaka│ └──────────────┘
Since the task was shown with JSON-Data, I want to also show how to tackle this with JSON-Data in APL.
promo2←{(⊂'')~⍨(⊂⍵.(min_orders min_price)){(⍺[1]≤+/⍺[2]≤⍵.hist)/⍵.id}¨⍵.customers}
