Wanda brought 90 pieces of bread, three times the number of treats, so Wanda brought 90/3 = <<90/3=30>>30 treats.
Wanda brought half as many treats as Jane, which means Jane brought 30*2 = <<30*2=60>>60 treats.
The total number of pieces of bread Jane brought is 75% of the number of treats, which means Jane brought 0.75 * 60 = 45 pieces of bread.
Wanda and Jane brought a total of 30 treats+60 treats+45 pieces of bread + 90 pieces of bread = <<30+60+45+90=225>>225
