Let the number of dimes be D and quarters, Q
\n" ); document.write( "Then we get the system: \"system%28D+%2B+Q+=+36%2C+.1D+%2B+.25Q+=+5.85%29\"
\n" ); document.write( "You solve the system for Q: the number of quarters, since that's what's being sought.
\n" ); document.write( "OR
\n" ); document.write( "You don't have to have a system. You can solve with just one variable, as follows:
\n" ); document.write( "Let the number of quarters be Q
\n" ); document.write( "Then number of dimes = 36 - Q
\n" ); document.write( "We then get the following equation: \"matrix%281%2C3%2C+.25Q+%2B+.1%2836+-+Q%29%2C+%22=%22%2C+5.85%29\"
\n" ); document.write( "You solve the system for Q: the number of quarters, since that's what's being sought. \n" ); document.write( "
