Diana has a total of 100 dimes and quarters.
\n" ); document.write( "If the total value of the coins is $13.75, how many quarters does she have?
\n" ); document.write( ":
\n" ); document.write( "Write two equations, we will use substitution here
\n" ); document.write( ":
\n" ); document.write( "total coin equation
\n" ); document.write( "d + q = 100
\n" ); document.write( "d = (100-q)
\n" ); document.write( "and
\n" ); document.write( "total value equation
\n" ); document.write( ".10d + .25q = 13.75
\n" ); document.write( "Replace d with (100-q)
\n" ); document.write( ".10(100 - q) + .25q = 14.75
\n" ); document.write( "10 - .10q + .25q = 13.75
\n" ); document.write( ".15q = 13.75 - 10
\n" ); document.write( ".15q = 3.75
\n" ); document.write( "q = \"3.75%2F.15\"
\n" ); document.write( "q = 25 quarters
\n" ); document.write( ":
\n" ); document.write( "I'll let you find the number of dimes, check the solutions in the value equation \n" ); document.write( "
