Question 1140809
.


            This problem is to be solved mentally.



<pre>
An attentive reader will notice momentarily from the condition, that the difference in costs  $52 - $37 = $15  

is exactly the cost of  16 lb - 10 lb = 6 lb of the cinnamon tea.



So the price of the cinnamon tea is  {{{15/6}}} = 2.50 dollars per pound.



Then the cost of 4 lb of the spice tea is  37 - 10*2.5 = 37 - 25 = 12 dollars;

hence, the price of the of the spice tea is  12/4 = 3 dollars per pound.



<U>ANSWER</U>.  $2.50 per pound for the cinnamon tea and $3.00 per pound for the spice tea.
</pre>

Solved.
