Question

Annie and her girlfriend, Estella, were talking about how heavy their backpacks were as they prepared for a hike. They decided to weigh them to see which was heavier. Annie’s backpack weighed 18.2 lb. and Estella’s weighed 16.75 lb. How much heavier was Annie’s backpack?

Answer 1

To find out how much heavier Annie's backpack is, we need to subtract Estella's backpack weight from Annie's backpack weight: 18.2 lb - 16.75 lb = <<18.2-16.75=1.45>>1.45 lb.
Annie's backpack is 1.45 lb heavier than Estella's backpack. Answer: \boxed{1.45}.
