One taxi cab charges $2.00 plus 75 cents per mile while a second taxi charges 75 cents plus 80 cents per mile.
\n" ); document.write( " For what length trip would the fee charge by each taxi be the same?
\n" ); document.write( ":
\n" ); document.write( "Not sure how you would get a negative, but lets do it this way
\n" ); document.write( ":
\n" ); document.write( "Let d = trip distance that both cabs would cost the same
\n" ); document.write( ":
\n" ); document.write( "2nd cab cost = 1st cab cost
\n" ); document.write( ".80d + .75 = .75d + 2.00
\n" ); document.write( ".80d - .75d = 2.00 - .75
\n" ); document.write( ".05d = 1.25
\n" ); document.write( "d = 1.25/.05
\n" ); document.write( "d = 25 miles
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "See if this is true, find the cost for each at 25 mi
\n" ); document.write( ".80(25) + .75 = $20.75
\n" ); document.write( ".75(25) + 2.00 = 20.75 \n" ); document.write( "
\n" );
