What is the answer and how do u do it??

The information given states that 500 people were surveyed, so that means that the percentages given are percents of 500. To find how many people prefer to watch television Monday night, we need to find out what 20% of 500 is. To do that, you can convert 20% to a decimal (0.2) and multiply it by 500. The answer is 100, so 100 people prefer television on a Monday night.

Next, find how many people prefer television on a Thursday night. To do that, we need to find out what 12% of 500 is. You can do that by converting 12% to a decimal (0.12) and multiply it by 500. The answer is 60, so 60 people prefer television on a Thursday night.

Finally, since you're trying to find how many more people prefer watching television on Monday night than the number of people who prefer Thursday night, you would subtract the two groups. So, 100-60=40. The final answer is D, 40.

I really hope this helps! Feel free to ask questions. ☺
