Question

8 meters increased by 25 percent

Answer 1

1.25x8=10meters

100% (final-initial)/initial = % changed
100%(final-8 meters)/8 meters =25%

100%(final-8 meters)/8 meters/100 = (final-8 meters)/ 8 meters
25%/100=.25

So, (final-8 meters)/ 8=.25

(final-8meters)/8x8= final-8
.25x8= 2

So, final-8=2

final-8+8=final
2+8=10

Final=10 meters
