Algebra.Com's Answer #20590 by longjonsilver(2297) You can put this solution on YOUR website! from 52 to 472 is an actual increase of 420.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Percentage-wise, we ALWAYS use the ORIGINAL. Here, the original file size was 52. So fractional increase is 420/52\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Therefore, the percentage increase is (420/52)*100 --> 807.69% \n" ); document.write( "--> 808%... answer C\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "jon. \n" ); document.write( " \n" ); document.write( " |
