Paul E. Bank has $2.25 in quarters and dimes. He has 15 coins.
\n" ); document.write( " Find the number of quarters and dimes he has.
\n" ); document.write( ":
\n" ); document.write( "Let d = no. of dimes
\n" ); document.write( "Let q = no. of quarters
\n" ); document.write( ":
\n" ); document.write( "Write an equation for each statement.
\n" ); document.write( "\"
\n" ); document.write( "\" Paul E. Bank has $2.25 in quarters and dimes.\"
\n" ); document.write( ".10d + .25q = 2.25
\n" ); document.write( ":
\n" ); document.write( "\" He has 15 coins.\"
\n" ); document.write( "d + q = 15
\n" ); document.write( "We can use substitution here, change the equation to:
\n" ); document.write( "d = (15-q)
\n" ); document.write( ":
\n" ); document.write( "Replace d with (15-q) in the second equation
\n" ); document.write( ".10(15-q) + .25q = 2.25
\n" ); document.write( "1.5 - .10q + .25q = 2.25
\n" ); document.write( "-.10q + .25q = 2.25 - 1.5
\n" ); document.write( ".15q = .75
\n" ); document.write( "q = .75/.15
\n" ); document.write( "q = 5 quarters
\n" ); document.write( "I'll let you find the number of dimes, check solutions in the 1st equation \n" ); document.write( "
\n" );
