Mike's house payments rose from $295 to $310 per month. In the past 12 months, he paid $3615. How many payments at each rate did he make?
\n" ); document.write( ":
\n" ); document.write( "Let x = number of $310 payments
\n" ); document.write( "Let (12-x) = number of $295 payments
\n" ); document.write( ":
\n" ); document.write( "$310 payments + $295 payments = 3615
\n" ); document.write( " 310x + 295(12-x) = 3615
\n" ); document.write( " 310x + 3540 - 295x = 3615
\n" ); document.write( " 310x - 295x = 3615 - 3540
\n" ); document.write( " 15x = 75
\n" ); document.write( " x = 75/15
\n" ); document.write( " x = 5 ea $310 payments
\n" ); document.write( ":
\n" ); document.write( "12 - 5 = 7 ea $295 payments
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check: 5(310) + 7(295) = 3615\r
