You can put this solution on YOUR website!
Don't know. You should ask at Kinko's
\n" ); document.write( "Your problem doesn't really give enough info.
\n" ); document.write( "But we can make a bunch of assumptions.
\n" ); document.write( "3 in by 5 in is not a poster but an index card same as a picture postcard.
\n" ); document.write( "Perhaps you mean feet and not inches.
\n" ); document.write( "3*5=15 square inches
\n" ); document.write( "6*10=60 square inches which is 4 times the postcard
\n" ); document.write( "So it should cost 4 times as much.
\n" ); document.write( "6 by 10 is just a large postcard not a poster either.
\n" ); document.write( "4*6.50=$26.00 for a large postcard
\n" ); document.write( "
