Question

NEED HELP FAST!!! Find the percent of increase from 260 to 430. Round to the nearest tenth of a percent if necessary.

a) 0.7%
b) 39.5%
c)60.5%
d)65.4%

Answer 1

You started out with 260, and increased to 430.
The amount you increased was (430 - 260) = 170

170 is (170/260) = 65.4% 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% .
