you have a newspaper add 5cm x 12cm costing $1500.00
\n" ); document.write( "if you double the length how much will the add cost?
\n" ); document.write( "i doubled the space of the ad which would cost $3000.00
\n" ); document.write( "then i doubled the length and came up with $2250.00
\n" ); document.write( "-------------------------------
\n" ); document.write( "If you double the length you will double the area of the add,
\n" ); document.write( "so $3000 seems like a reasonable cost.
\n" ); document.write( "--------
\n" ); document.write( "If you ALSO double the length you will multiply the area by 4.
\n" ); document.write( "So the cost should be 1500*4 = $6000
\n" ); document.write( "==================================================
