\n" ); document.write( "\n" ); document.write( "Let represent the amount charged per mile. Let represent the daily fee.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In the first situation, where the mileage fee represents the cost of traveling 300 miles, that cost can be expressed as . That is, the number of miles traveled times the cost per mile. Furthermore, the cost for the daily fee for the 3 days is represented by , i.e. the number of days times the daily fee. The sum of the two is given as $69, hence:\r

\n" ); document.write( "\n" ); document.write( "Now all you have to do is solve the system for the ordered pair . Hint: Since the larger coefficient on is an integer multiple of the other, this system lends itself nicely to the Elimination method. Just multiply the first equation by -2 and proceed.\r
