Debbie uses 8 ounces of apples to make one serving of applesauce. How many servings of applesauce can she make with 6 pounds of apples?

Since there are 16 ounces in 1 pound, then 6 pounds is equal to 6 x 16 = <<6*16=96>>96 ounces.

Therefore, Debbie can make 96/8 = <<96/8=12>>12 servings of applesauce. Answer: \boxed{12}.
