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 o
f those students also signed up for canoeing.

Approximately what percentage of students signed up for neither canoeing nor trekking?
10%
12%
38%
32%

Answer: The answer is 32%
Step-by-step explanation: <u>10% is the wrong answer!</u> I see everybody saying 10% but it is wrong let me show you:
I linked the table down below and by doing simple math like addition and subtraction I filled in the missing numbers on the 2-way table. So what you have to do to get the percentage is take 38% (which is the total of of no-canoe and no-trek students) and divide it by 120 (the overall total). This will get you a long decimal of 0.31666667, but then you are going to multiply the decimal by 100; 0.31666667*100, to get 31.666667 which is your percentage and we will round it up to <u>32%</u>
good luck

Answer:
15 days
Step-by-step explanation:
Let x be the number of days needed for B to complete the job. Then x-5 is the number of days needed for A to complete the job.
In 1 day,
- A completes
of all work;
- B completes
of all work.
Hence, in 1 day both A and B complete of all work. A and B working together can do a work in 6 days. Then
Solve this equation:
If then
that is impossible. So, B needs 15 days to complete the work alone.
