Answer 1

Answer:

2.25%

Step-by-step explanation:

let the initial population be 100

first year it increases by 100 of 15%=100×$\frac{15}{100}$

                                                          =15

⇒100+15=115

next year it decreases by 15% of 115=115×$\frac{15}{100}$

                                                           =$\frac{69}{4}$=17.25

⇒115-17.25=97.75

decrease =100-97.75=2.25

decrease %= $\frac{2.25}{100}$×100%=2.25%
