document.write( "An attentive reader will notice momentarily from the condition, that the difference in costs  $52 - $37 = $15  \r\n" );
document.write( "\r\n" );
document.write( "is exactly the cost of  16 lb - 10 lb = 6 lb of the cinnamon tea.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So the price of the cinnamon tea is  \"15%2F6\" = 2.50 dollars per pound.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then the cost of 4 lb of the spice tea is  37 - 10*2.5 = 37 - 25 = 12 dollars;\r\n" );
document.write( "\r\n" );
document.write( "hence, the price of the of the spice tea is  12/4 = 3 dollars per pound.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  $2.50 per pound for the cinnamon tea and $3.00 per pound for the spice tea.\r\n" );
