Question

How many pounds of mixed nuts selling for $4.75 per pound should be mixed with 10 pounds of
dried fruit selling for $5.50 per pound to obtain a trail mix that sells for $4.95 per pound?

Answer 1

27.5 lbs of mixed nuts must be added

10 * 5.5 + x * 4.75 = (10 + x)* 4.95 => 55 + 4.75x =49.5 + 4.95x => 5.5 = .20x
