We know that the total cost will be 30 lb * $3/lb = $90. We can thus set up an equation such that: 90 = 3.5*b + 2*(30-b), where b is the weight of blackberries and 30-b represents that which is not blackberries, that is, the blueberries. We solve the equation as: 90 = 3.5b +60 -2b = 1.5b + 60 30 = 1.5b b = 20 Thus 20 lbs of blackberries (and 10 lbs of blueberries) are needed.
