s = d/t
\n" ); document.write( "d = st
\n" ); document.write( "---
\n" ); document.write( "d = 55*1.5
\n" ); document.write( "d = 82.5 miles to work
\n" ); document.write( "---
\n" ); document.write( "spent per mile:
\n" ); document.write( "(1/30 gallon/miles) * (3.45 dollars/gallon) = 0.115
\n" ); document.write( "---
\n" ); document.write( "total spent one-way:
\n" ); document.write( "(82.5 miles) * (1/30 gallon/miles) * (3.45 dollars/gallon) = 9.4875
\n" ); document.write( "---
\n" ); document.write( "answer:
\n" ); document.write( "expense per mile = $0.115
\n" ); document.write( "expense one-way to work = $9.49
