Luis es repartidor de leche el tiene 534 bolsas y las reparte entre cierto numero de tienda de modo que a cada le corresponde 28
OlgaM077 [116]
The first thing we must keep in mind is that there are 2 bags left over.
 Therefore, Luis distributed:
 534-2 = 532
 The number of bags will be:
 N = (total amount distributed) / (amount distributed per store)
 Substituting we have:
 N = (532) / (28)
 N = 19
 Answer:
 
Luis distributed milk for 19 stores.
