of the bag to fill a bird feeder in her garden. Then, she puts 0.25 pounds in a dish to give to her pet canaries. How much birdseed does she have left?

1 answer

Nancy uses 3/4 * 3.5 = <<3/4*3.5=2.625>>2.625 pounds of birdseed to fill the bird feeder.
After filling the bird feeder, she has 3.5 - 2.625 = <<3.5-2.625=0.875>>0.875 pounds of birdseed left.
Then she puts 0.25 pounds in a dish for her pet canaries.
Therefore, Nancy has 0.875 - 0.25 = <<0.875-0.25=0.625>>0.625 pounds of birdseed left. Answer: \boxed{0.625}.
