Answer: 35.88
Step-by-step explanation: So if something is marked up by 8.7% it means, it is 108.7% of the original number.
So we can convert 108.7% to a decimal by dividing 108.7 by 100, which equals 1.087.
So if we want to find the original number, all we have to do is divide 39 by 1.087.
This will give us 35.88 as the original number rounded to the nearest tenth.

Step-by-step explanation:
So to find average, we add up the values, and divide it by how many values there are in total.
27 + 12 + 31 + 19 + 23 + 11 + 17 = 140.
There are 7 numbers. Which means we divide 140 by 7.
140 / 7 = 20 is the average.
Also, if you notice, most of the numbers "kind of" circulate around 20.
