She donates 30% of her 80 pairs of shoes so that’s .30*80 = <<30*.01*80=24>>24 pair of shoes she donates
She had 80 shoes in her collection and donates 24 so that leaves 80-24 = <<80-24=56>>56 pairs of shoes
She now has 56 pairs of shoes and buys 6 more pairs so her collection is now 56+6 = <<56+6=62>>62 pairs of shoes
