What single percentage change is equivalent to a 11% decrease followed by a 21% increase?
1 answer:
Answer:
7.69% increase
Step-by-step explanation:
Let our initial number be 100
11% decrease will be;
100- 0.11(100) = 100-11 = 89
A 21% increase will be;
89 + 21% of 89
89 + 0.21(89)
= 107.69
difference from the starting is 107.69 - 100 = 7.69
The percentage is 7.69% increase
