At camp Wonka, there are 96 campers. Two-thirds of the campers are boys, and the remaining one-third are girls. 50% of the boys want to toast marshmallows and 75% of the girls want to toast marshmallows. If each camper gets one marshmallow to toast, how many marshmallows do they need? Let's think first. Chain of thought:

The girls make up one - third of the campers, so there are 96 / 3 = 32 girls. The boys make up two - thirds of the campers, so there are 32 + 32 = 64 boys. There are 32 x 75% = 24 girls who want to toast marshmallows. There are 64 x 50% = 32 boys who want to toast marshmallows. They need 24 + 32 = 56 marshmallows.
Therefore, the answer is 56.
