Formula
In order to increase a number by p percent, multiply the given number by (1 + p100)
N1 = N · (1 + p100)
where:
N - source number
p - percent
N - source number
p - percent
Let's increase 200 by 30%:
200 · (1 + 30100) = 200 · 1,3 = 260
So, 200 + 30% is 260.
200 · (1 + 30100) = 200 · 1,3 = 260
So, 200 + 30% is 260.
