\n" ); document.write( "If 28 students pay $30 each, then that's 28*30 = 840 dollars total.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now consider only 21 students attend. If the total cost stays at $840, then each student now has to pay 840/21 = 40 dollars.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The cost per person has increased by $10 since 40-30 = 10.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Answer: $40 per person
\n" ); document.write( "
