Every day, Rachel walks by the same grocery store on her way home from school. Most days she goes in to buy a snack. Today she's craving peanut-butter pretzels, so she fills a small bag from the bulk bin section. After weighing the bag on the scale, she removes 0.25 pounds of pretzels. Now the bag weighs 0.35 pounds. Which equation can you use to find the weight w of the bag before Rachel removes the pretzels? Solve this equation for w to find the weight of the bag before Rachel removes the pretzels.
