\n" ); document.write( "Colin has a jar containing only 5-cent and 20-cent coins. In total, there are 31 coins with a total value of $3.50. How many of each type coin does Colin have?
\n" ); document.write( "

Let number of 5-cent coins be F
\n" );
document.write( "Then number of 20-cent coins is: 31 - F
\n" );
document.write( "We then get the following VALUE equation: .05F + .2(31 - F) = 3.5
\n" );
document.write( "Solve this for F, the number of 5-cent coins.
\n" );
document.write( "Subtract value of F from 31 to get number of 20-cent coins.
\n" );
document.write( "Note that the value of F MUST be an integer.\r
\n" );
document.write( "\n" );
document.write( "It's as simple as that...nothing COMPLEX!! \n" );
document.write( "

\n" );
