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( "\" There are 15 more nickels than quarters.\"
\n" ); document.write( "n = (q+15)
\n" ); document.write( ":
\n" ); document.write( "\"The total value is $2.55.\"
\n" ); document.write( ".05n + .25q = 2.55
\n" ); document.write( "Replace n with (q+15)
\n" ); document.write( ".05(q+15) + .25q = 2.55
\n" ); document.write( ".05q + .75 + .25q = 2.55
\n" ); document.write( ".05q + .25q = 2.55 - .75
\n" ); document.write( ".30q = 1.80
\n" ); document.write( "q = \"1.80%2F.3\"
\n" ); document.write( "q = 6 quarters
\n" ); document.write( "then
\n" ); document.write( "n = 6 + 15
\n" ); document.write( "n = 21 nickels
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check this
\n" ); document.write( ".05(21) + .25(6) =
\n" ); document.write( "1.05 + 1.50 = 2.55\r
