If Tim has $4.50 in change, over dimes, nickels, and quarters,..then:
\n" ); document.write( "25Q+10D+5N=450. Using dimes as our standard, we get:
\n" ); document.write( "Q=D+4;
\n" ); document.write( "N=3D, so:
\n" ); document.write( "25(D+4)+10D+5(3D)=450
\n" ); document.write( "25D+100+10D+15D=450
\n" ); document.write( "50D=350
\n" ); document.write( "D=7
\n" ); document.write( "If D=7, then Q=11, and N=21.
\n" ); document.write( "Let's see;
\n" ); document.write( "11(25)+10(7)+21(5)=275+70+105=450
\n" ); document.write( "Tim has 11 quarters, 7 dimes, and 21 nickels!!!!!!!!
\n" ); document.write( "
\n" );
