Question 760705
I would solve this problem using a chart:
  Type         : P (money or percentage of item):A (amount of item): Total
C)chamomile tea:$18.20     <==multiply==>       :x    gets==>           :18.20x
o)orange tea   :$12.25 <==multiply==>           :12  gets==>             :147.00
m)mixture     :$14.63 <==multiply==>           :x+12 gets==>      :14.63x+175.56

Now using the information on the chart, we can make an equation. Since it is a mixture, we add both teas to make this mixture so the equation is the total of c tea and o tea=mixture of tea. Which in math is:18.20x+147.00=14.63x+175.56
From here you simplify the equation and solve for x. 

                   :)See if you can solve it from here, good luck!!;)
