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>
The correct answer is $44.20. If we add up all the tips, the total is $442. If we divide this by the number of days (10), then we find the mean. 442 / 10 = 44.2
