1. **State the problem:** Ms. Finley has 5 boxes of granola bars. Each day, she packs 1 granola bar in each of her 2 children's lunches. We need to find how many school days the granola bars will last. 2. **Analyze the graph:** The graph shows the number of granola bars increasing by 10 for each box number. So, each box contains 10 granola bars. 3. **Calculate total granola bars:** Since Ms. Finley has 5 boxes and each box has 10 bars, total bars are: $$5 \times 10 = 50$$ 4. **Calculate daily usage:** She packs 1 bar per child per day, and she has 2 children, so daily bars used are: $$2 \times 1 = 2$$ 5. **Calculate how many days the bars will last:** Divide total bars by daily usage: $$\frac{50}{2} = 25$$ 6. **Answer:** The granola bars will last for 25 school days.
