1. The problem asks which city had the greatest total snowfall over 5 weeks. 2. To find the total snowfall for each city, sum the snowfall amounts for all 5 weeks. 3. Let $S_A$ be the total snowfall for City A and $S_B$ for City B. 4. Calculate $S_A = \text{Week 1}_A + \text{Week 2}_A + \text{Week 3}_A + \text{Week 4}_A + \text{Week 5}_A$. 5. Calculate $S_B = \text{Week 1}_B + \text{Week 2}_B + \text{Week 3}_B + \text{Week 4}_B + \text{Week 5}_B$. 6. Compare $S_A$ and $S_B$. 7. The city with the larger total snowfall is the answer. Since the exact snowfall values are not provided, you need to add the bar heights from the graph for each city and compare. If $S_A > S_B$, City A had the greatest total snowfall. If $S_B > S_A$, City B had the greatest total snowfall. If $S_A = S_B$, they had equal snowfall.
