Hi! :)

The answer is A, here's why:

When tipping at a restaurant, first you need to figure out how much you're tipping. You need to move the decimal left 2 places on how much you tip. So for 20%, you get .20

Then to figure out how much to tip for 20%, you would multiply that .20 by how much the bill was and that's your tip. So .20*30=6. Your tip should be 6 dollars, and the formula for that is t=.20<em>b</em>

A would be the answer to this problem. To find any tip, you usually calculate it by percentage . So to find the percentage of the bill, you multiply it by the percentage which is divided by 100. So A, t=0.20b would be the answer.

The answer to this question would be the last choice (this data has no outliers)

Explanation: The reason for this is that an outlier is basically any number or value that kind of stands off or is very separated from a set of data.

For example, if I had the numbers 1,2,3,2,9,5,7,5,8,4 and 47, 47 would definitely be an outlier as it's significantly greater than the rest of the data.

The data shown in your question doesn't vary a lot though, (it's contained within a range of 65 and 80- no number seems to be radically different).
