1. **State the problem:** We analyze the sales data of hotdogs and hamburgers from a double bar graph for Monday to Friday. 2. **Identify sales per day from the graph:** - Monday: Hamburgers = 45, Hotdogs = 40 - Tuesday: Hamburgers = 40, Hotdogs = 35 - Wednesday: Hamburgers = 35, Hotdogs = 25 - Thursday: Hamburgers = 20, Hotdogs = 20 - Friday: Hamburgers = 25, Hotdogs = 20 3. **Answer each question:** a. Each bar represents the number of items sold as above. b. More hamburgers sold on Monday than Tuesday: $$45 - 40 = 5$$ c. Busiest day is the day with the highest total sales: Monday total = $$45 + 40 = 85$$ Tuesday total = $$40 + 35 = 75$$ Wednesday total = $$35 + 25 = 60$$ Thursday total = $$20 + 20 = 40$$ Friday total = $$25 + 20 = 45$$ So, Monday is the busiest day. d. Total hotdogs sold during the week: $$40 + 35 + 25 + 20 + 20 = 140$$ e. Fewest hamburgers sold on Thursday (20). f. Rolls and buns are bought in dozens (12 items per dozen). Calculate dozens per day: | Day | Hamburgers | Hotdogs | Hamburger Buns (dozens) | Hotdog Rolls (dozens) | |---------|------------|---------|------------------------|----------------------| | Monday | 45 | 40 | $$\lceil \frac{45}{12} \rceil = 4$$ | $$\lceil \frac{40}{12} \rceil = 4$$ | | Tuesday | 40 | 35 | $$\lceil \frac{40}{12} \rceil = 4$$ | $$\lceil \frac{35}{12} \rceil = 3$$ | | Wednesday| 35 | 25 | $$\lceil \frac{35}{12} \rceil = 3$$ | $$\lceil \frac{25}{12} \rceil = 3$$ | | Thursday| 20 | 20 | $$\lceil \frac{20}{12} \rceil = 2$$ | $$\lceil \frac{20}{12} \rceil = 2$$ | | Friday | 25 | 20 | $$\lceil \frac{25}{12} \rceil = 3$$ | $$\lceil \frac{20}{12} \rceil = 2$$ | (g) Money taken on Monday: - Hotdogs: 40 sold at 5.50 each - Hamburgers: 45 sold at 8.00 each Calculate total: $$40 \times 5.50 = 220$$ $$45 \times 8.00 = 360$$ Total money taken: $$220 + 360 = 580$$ (h) Sales are best on Monday possibly because it is the first day of the week when students buy more snacks after the weekend or due to special promotions. **Final answers:** - a: Bars represent exact sales numbers listed. - b: 5 more hamburgers on Monday than Tuesday. - c: Monday is busiest day. - d: 140 hotdogs sold in the week. - e: Fewest hamburgers on Thursday. - f: Dozens of buns and rolls as per table above. - g: 580 money units taken on Monday. - h: Sales best on Monday likely due to higher demand after weekend.
