I am choosing P to represent the # of photos taken on day 2 which makes day 3 equal to 2P. Day 1 is a constant.
\n" ); document.write( "Day1: 10
\n" ); document.write( "Day2: P
\n" ); document.write( "Day3: 2P
\n" ); document.write( ":
\n" ); document.write( "all photos...... $\"10%2BP%2B3P=T\"$ where T is the total of all photos taken
\n" ); document.write( ":
\n" ); document.write( "simplified: 10+3P=T
\n" ); document.write( ":
\n" ); document.write( "if day 2 is 12 then $\"highlight%28T=10%2B3%2812%29=46%29\"$ pho \n" ); document.write( "
