You can put this solution on YOUR website! It is given that there will be 70 lb of mixture of the teas
Also given is that the mixture will sell for $2.75 / lb.
Let = lbs of $3.45 tea
Let = lbs of $1.75 tea
Since and account for the whole mixture,
multiply both sides by -1.75
(1)
(2)
Add (1) and (2)

So, I get lbs of the $3.45 tea and lbs of the $1.75 tea
