Question

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%

Answer 1

32%

Explanation:

Because its 32% because I did 10% and got it wrong, it says 32%, just don't pick 10%

Answer 2

Answer: The answer is 32%

Step-by-step explanation: 10% is the wrong answer! 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 32%

good luck
