If all 20 coins were dimes, she would have $2.00
\n" ); document.write( "She has $1.20 more than this. A quarter is .15 more than a dime.
\n" ); document.write( "$1.20 / .15 = 8
\n" ); document.write( "8 of the coins are quarters. 8*.25 = 2.00
\n" ); document.write( "That leave 12 coins as dimes. 12*.10 = 1.20
\n" ); document.write( "2.00 + 1.20 = $3.20
\n" ); document.write( "
\n" );
