d+q=25
\n" ); document.write( ".10d+.25q=4.15
\n" ); document.write( "first thing you should notice is the 15 cents
\n" ); document.write( "2 dimes= 20 cents and 1 quarter =25 cents so you need to find the combination that makes the 15 cents. 3 quarters gives 75 cents and addin 4 dimes gets 1.15
\n" ); document.write( "min q=3 =.75 +.40=1.15
\n" ); document.write( "min d=4
\n" ); document.write( "3q+4d=7 coins
\n" ); document.write( "25-7=18 coins left
\n" ); document.write( "18d=1.80 guess, and lets you know you will need a few more quarters
\n" ); document.write( "4.15-1.15=3.00
\n" ); document.write( "we need 3 dollars
\n" ); document.write( "4q=1.00
\n" ); document.write( "4q=1.00
\n" ); document.write( "10d=1.00
\n" ); document.write( "3+4+4=11quarters
\n" ); document.write( "4+10=14dimes
\n" ); document.write( "11q+14d=25coins
\n" ); document.write( "
\n" );
