John works two part-time jobs for a total of 25 hours per week.
\n" ); document.write( " Job A pays $7.50 per hour and Job B pays $8.40 per hour.
\n" ); document.write( " How many hours did he work at each job if he made $200.10 this week?
\n" ); document.write( ":
\n" ); document.write( "Let a = no. of hrs worked at job A
\n" ); document.write( "Let b = no. of hrs worked at job B
\n" ); document.write( ":
\n" ); document.write( "Write an equation for each statement;

\n" ); document.write( "\"John works two part-time jobs for a total of 25 hours per week.\"
\n" ); document.write( "a + b = 25
\n" ); document.write( "a = (25-b); we can use this form for substitution
\n" ); document.write( ";
\n" ); document.write( "\"Job A pays $7.50 per hour and Job B pays $8.40 per hour.he made $200.10\"
\n" ); document.write( "7.50a + 8.40b = 200.10
\n" ); document.write( "replace a with (25-b)
\n" ); document.write( "7.50(25-b) + 8.40b = 200.10
\n" ); document.write( "187.50 - 7.50b + 8.40b = 200.10
