88 pieces
Explanation:
The girls picked up 8 for every 5 the boys picked up
The top picture shows 8 for the girl and 5 for the boys
The difference between the boys and the girls is 3 pieces
The girls picked up 33 more pieces
33/3 =11
The multiplier is 11
8*11 is 88 pieces
Lets check
Girls had 88 pieces
The boys had 5*11 = 55 pieces
88-55 = 33
