You can put this solution on YOUR website!
let n = no. of nickels
\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( "\"Maria has a collection of coins; the value of the collections is $7.50.\"
\n" ); document.write( ".05n + .25q = 7.50
\n" ); document.write( ":
\n" ); document.write( "\" There are six more quarters than nickels.\"
\n" ); document.write( "q = (n+6)
\n" ); document.write( ":
\n" ); document.write( "Replace q in the 1st equation with (n+6), find n
\n" ); document.write( ".05n + .25(n+6) = 7.50
\n" ); document.write( ":
\n" ); document.write( "I think you can do this now.
