The value of Lindsey's 9 coins is $0.57. She has 3 kinds of coins. What kinds of coins does Lindsey have? How many of each kind does she have? ( hint there is more than one answer)
\n" ); document.write( "

\n" ); document.write( "Note that \".57c\" consist of AT LEAST 2 pennies\r
\n" ); document.write( "\n" ); document.write( "If 1 \"50c\" coin, or \"1%2F2\"-dollar, and 2 pennies, then 6 (9 - 1 - 2) more coins are needed to make the remaining \"5c\".
\n" ); document.write( "This is NOT POSSIBLE!! Therefore, no \"1%2F2\"-dollar, or \"50c\" coins are included.\r
\n" ); document.write( "\n" ); document.write( "Besides yours, I didn't see any other combination involving quarters.\r
\n" ); document.write( "\n" ); document.write( "If 4 \"10c\" coins, or 4 dimes, and 2 pennies, then 3 (9 - 4 - 2) more coins are needed to make the remaining \"15c\".
\n" ); document.write( "This is POSSIBLE, as 3 nickels do make \"5c\". Therefore, she could have:

\n" ); document.write( "\n" ); document.write( "I didn't see any other combination involving dimes and nickels.\r
\n" ); document.write( "\n" ); document.write( "Besides the combination you found, I don't see any other. Thereby, only two seem to exist. \n" ); document.write( "
