How many pounds of chamomile tea that costs $18.50 per pound must be mixed with 17 lb of orange tea that costs $12.25 per pound to make a mixture that costs $14.25 per pound?
Let x = number of pounds of chamomile tea
17 = number of pounds of orange tea
17 + x = total number of pounds
18.50x + 12.25(17) = 14.25(17 + x)
18.50x + 208.25 = 242.25 + 14.25x
4.25x = 34.00
x = 8 pounds
