I believe that you need to find 15% of 60 so it’s 9
Put the numbers in order from smallest to largest:
21,34,45,53,71,88
Since there are an even amount of numbers you must take the middle two and find the average(add them together then divide by 2)
45+53=98
98/2=49
The answer is 43 when you add 29 back to 57 then divide by 2
