The cost of a taxi ride is given by C=rd+a, where r is the rate per one-fifth mile, d is the trip distance in terms of the number of one-fifth-mile units in the trip, and a is the flag-drop fee (an automatic charge created when the meter is started).
\n" ); document.write( " Solve the equation for the mileage rate r.
\n" ); document.write( "write it:
\n" ); document.write( "rd + a = C
\n" ); document.write( "rd = C - a
\n" ); document.write( "divide both sides by d
\n" ); document.write( "r = $\"%28%28C-a%29%29%2Fd\"$ , (rate is per 1/5 mile)\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
