Peggy has 6 dolls and her grandmother gave her 30 so that’s 6+30 = <<6+30=36>>36 dolls
Over the holidays, Peggy is gifted half the number of dolls her grandmother gave her, so she receives 30/2 = <<30/2=15>>15 more dolls
Peggy had 36 dolls and received another 15 for a total of 36+15 = <<36+15=51>>51 dolls
