I do i posted a lot of math do the one that i posted a long time ago
Easy, 100 x 3 is 300 pounds, 5 x 3 is 15, so 15 pounds. :)
F(x) = x^2 + 1 f(10)
f(10) = 10^2 + 1
f= 101
You started out with 260, and increased to 430.
The amount you increased was (430 - 260) = 170
170 is (170/260) = <em>65.4%</em> of what you started with.
============================
Another way:
The new amount is (430/260) of the old amount.
430 / 260 = 1.654 = 165.4%
The original amount was 260.
You started with 100% of it.
You ended up with 165.4% of it.
That's an increase of 65.4% .
