Combining Percents

50% is better

There's a 100 caribou, then in 1 year it increase 10%
and it will have 110 caribou, after 2 years it increase 20%
which will make 132 caribou.
There will be 132 caribou in 2 years.

for the "show you know" my price will be 800
Store A:
50% off one day only
50% is the same as half, you divide it into 2 and the answer will be 400

Store B:
25% off one day followed by 25% off the reduced price the second day
first day:
0.25 x 800 = 200
800 - 200 = 600
the first day, it will be 600
second day:
0.25 x 600 = 150
600 - 150 = 450
the second day, it will be 450.

50% is better then 25%
