Let $\"N\"$ , $\"D\"$ , $\"Q\"$ be the number of each coin he has.
\n" ); document.write( "1. $\"D=2%2AN\"$
\n" ); document.write( "2. $\"Q=D-2\"$
\n" ); document.write( "3. $\"0.05%2AN%2B0.10%2AD%2B0.25%2AQ=3.25\"$
\n" ); document.write( "Substitute 1 and 2 into 3,
\n" ); document.write( " $\"0.05%2AN%2B0.10%2A2%2AN%2B0.25%2A%28D-2%29=3.25\"$
\n" ); document.write( " $\"0.05%2AN%2B0.2%2AN%2B0.25%2A%282%2AN-2%29=3.25\"$
\n" ); document.write( "Multiply both sides by 100,
\n" ); document.write( " $\"5N%2B20N%2B25%282N-2%29=325\"$
\n" ); document.write( " $\"5N%2B20N%2B50N-50=325\"$
\n" ); document.write( " $\"75N=375\"$
\n" ); document.write( " $\"N=5\"$
\n" ); document.write( "Then from eq. 1,
\n" ); document.write( " $\"D=2%2A5\"$
\n" ); document.write( " $\"D=10\"$
\n" ); document.write( "Then from eq. 2,
\n" ); document.write( " $\"Q=D-2\"$
\n" ); document.write( " $\"Q=8\"$
\n" ); document.write( "He has 5 nickels, 10 dimes, and 8 quarters.
\n" ); document.write( " \n" ); document.write( "
