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?

Result

p =  54 %

Solution:

a=1807223+13=98 b=180 p=a/b 100=98/180 100490954.444454%a=180-72-23+13=98 \ \\ b=180 \ \\ p=a/b \cdot \ 100=98/180 \cdot \ 100 \doteq \dfrac{ 490 }{ 9 } \doteq 54.4444 \doteq 54 \%
