What they are really asking is for the graph of the function
\n" ); document.write( "\"+f+=+g%28t%29+\". The monthly charge would be the slope of the line
\n" ); document.write( "if I plot f versus months (t)
\n" ); document.write( "Use the point-slope formula
\n" ); document.write( "\"+%28+f+-+75+%29+%2F+%28+t+-+3+%29+=++%28+115+-+75+%29+%2F+%28+5+-+3+%29+\"
\n" ); document.write( "\"+%28+f+-+75+%29+%2F+%28+t+-+3+%29+=+40+%2F+2+\"
\n" ); document.write( "\"+%28+f+-+75+%29+%2F+%28+t+-+3+%29+=+20+\"
\n" ); document.write( "\"+f+-+75+=+20%2A%28+t+-+3+%29+\"
\n" ); document.write( "\"+f+=+20t+-+60+%2B+75+\"
\n" ); document.write( "\"+f+=+20t+%2B+15+\"
\n" ); document.write( "So, the monthly charge is $20 and the set fee is $15
\n" ); document.write( "for 8 months:
\n" ); document.write( "\"+f+=+20%2A8+%2B+15+\"
\n" ); document.write( "\"+f+=+160+%2B+15+\"
\n" ); document.write( "\"+f+=+175+\"
\n" ); document.write( "Aaron pays $175
\n" ); document.write( "
\n" );
