Well, it just tells you to find the percentage of change and I'm stuck at the equation part. It's difference divide original number. I tried that, but it didn't work when I actually checked it with the answer.

130-32. Then divide 107 by 23. And I got 4.6521739130434782608695652173913.

130-32 (typo should be 23). Then divide 107 by 23. And I got 4.6521739130434782608695652173913.

how would you express 4.6521739130434782608695652173913 as a percentage (Hint: 2 is expressed as 200%)
