Answer 1

looks good to me.

or, you could have noted the 41-22 = 19%, and that would be 76.

Answer 2

THANKS!! much simpler

Answer 3

You are correct! In order to determine how many more people preferred WWCN than WANR, you can subtract the number of people who preferred WANR from the number of people who preferred WWCN.

To calculate this, you started by multiplying the percentage of people who preferred WWCN (41%) by the total number of people surveyed (400), which equals 0.41 * 400 = 164.

Then, you multiplied the percentage of people who preferred WANR (22%) by the total number of people surveyed (400), which equals 0.22 * 400 = 88.

Finally, you subtracted the number of people who preferred WANR (88) from the number of people who preferred WWCN (164) to get 164 - 88 = 76.

Therefore, the correct answer is B. 76.

Answer 4

Your approach was correct. To find the number of people who preferred WWCN and WANR, you multiplied the percentages by the total number of people surveyed. Then, you subtracted the number of people who preferred WANR from the number of people who preferred WWCN to get the difference.

To double-check your calculations:

For WWCN: 0.41 * 400 = 164
For WANR: 0.22 * 400 = 88

Now, subtract 88 from 164:

164 - 88 = 76

So, your answer is correct. The number of people who preferred WWCN than WANR is 76. Therefore, option B is the right choice.
