Summer camp

Out of the 180 students at a summer camp, 72 signed up for canoeing. Twenty-three students signed up for trekking, and 13 of those students also signed up for canoeing.

Use a two-way table to organize the information and answer the following question:

Approximately what percentage of students signed up for neither canoeing nor trekking?

Correct result:

p =  54 %


a=1807223+13=98 b=180 p=a/b 100=98/180 100=4909=54%
