NEED HELP FAST!!! Find the percent of increase from 260 to 430. Round to the nearest tenth of a percent if necessary.
a_sh-v [17]

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% .
