I JUST TOOK THE TEST !!!!
Step-by-step explanation:
5x + 10 10
---------- = -------
121 11
make the bottom have same common denominator
10/11 x (10/10) = 100/121
Get rid of the denominator (for both now have 121 as a base)
5x + 10 = 100
5x + 10 (-10) = 100 (-10)
5x = 90
5x/5 = 90/5
x = 18
x = 18 is your answer
hope this helps

This means that we take the difference from 100% of 95 and 80% of 95, and get a 20% decrease.
