Mario paid $44.25 in taxi fare from the hotel to the airport. The cab charged $2.25 for the first mile plus $3.50 for each additional mile. How many miles was it from the hotel to the airport?
\n" ); document.write( "**
\n" ); document.write( "you can use the standard form of equation of a straight line to solve this problem:
\n" ); document.write( "y=mx+b, m=slope, b=y-intercept
\n" ); document.write( "For given problem:
\n" ); document.write( "let x=distance from hotel to airport
\n" ); document.write( "slope=$3.50/mi
\n" ); document.write( "y-intercept=$2.25
\n" ); document.write( "y=44.25
\n" ); document.write( "..
\n" ); document.write( "44.25=3.5x+2.25
\n" ); document.write( "3.5x=44.25-2.25=42
\n" ); document.write( "x=42/3.5=12
\n" ); document.write( "distance from hotel to airport=12 miles \n" ); document.write( "
