.25X+.10(36-X)=7.95
\n" ); document.write( ".25X+3.6-.10X=7.95
\n" ); document.write( ".15X=7.95-3.6
\n" ); document.write( ".15X=4.35
\n" ); document.write( "X=4.35/.15
\n" ); document.write( "X=29 NUMBER OF QUARTERS.
\n" ); document.write( "36-29=7 DIMES.
\n" ); document.write( "PROOF:
\n" ); document.write( ".25*29+.10*7=4.95
