Out of the 120 students at a summer camp, 72 signed up for canoeing. There were 23 students who 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?

10%
12%
38%
32%

Approx - 10% 


72 students signed up for canoeing + the 23 students who signed up for trekking + the 13 students who signed up for both = 108 students 

there are 120 students total, so you have to subtract 120 - 108 = 12 

Now to find the percentage, you have to divide the number of students who didn't sign up for either, by the total 

which is .1 = 10/100 = 10%
