Lizzy: There were 133 people at a camp. There were 33 more boys than girls. How many girls were at the camp?.
Me: Hmmm, let me think. I think this is the detailed solution:
If there were 33 fewer boys at camp, there would be the same number of both boys and girls or 133 - 33 = 100 people. That means that there were 100 / 2 = 50 girls at the camp. Final answer: 50.
