Can someone help me understand the question?
I must be sounding silly however my doubt is,
If 20% of students at a certain school went to a camping trip, then what is the point in asking the percentage of students at school who went to the camping trip?
Please read the question now;
[highlight]If 20 percent of the students at a certain school went to a camping trip AND took more than $100[/highlight], and 75 percent of the students who went to the camping trip did not take more than $100, what percentage of the students at the school went to the camping trip?
The highlighted part is one giant sentence and should be read together.
20- Students went to the trip AND also took more than $100
Say, x students went to the trip.
So, x-20 will be the percent of student who took less than or equal to $100 with them.
And it is given that this x-20=75% who went to the picnic
