# 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:

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

Our examples were largely sent or created by pupils and students themselves. Therefore, we would be pleased if you could send us any errors you found, spelling mistakes, or rephasing the example. Thank you!
