16- let x represent the number:
x+ (x+1)+(x+2)=100
collect like terms
3x+3=100
3x=97
x=~32 but we need an odd number so round to 31, since 33 would be too great
31+33+35=99
therefore, the three numbers are 31, 33, 35
To find the mean, add all the numbers together and divide by the amount of numbers there is
89 + 92 + 97 + 81 + 96 = 455
455/5 = 91
91 is Andrew's mean score, and is your answer
hope this helps

Step-by-step explanation:</h3>
Her discounted price was 100% - 20% = 80% of the original price. The service fee made it be 100% + 10% = 110% of that, so her final price was ...
... 110% × 80% = 88%
of the original ticket price.
This represents a discount of 100% - 88% = 12% from the original.
