The daily sales of a department store for one week are as follows
| Days | Mon | Tue. | Wed. | Thu. | Fri. | Sat. |
| Sales N | 1750 | 1000 | 3500 | 2250 | 1000 | 2500 |
(a) Present the above data in a bar graph. (The use of graph sheet is essential).
(b) Calculate the average utility curve.
Answer Details
(a) Bar graph of daily sales
Using a vertical scale of ₦500 per major division, plot the days on the horizontal axis and daily sales on the vertical axis. The completed bar graph is:
| Day | Monday | Tuesday | Wednesday | Thursday | Friday | Saturday |
|---|---|---|---|---|---|---|
| Sales (₦) | 1,750 | 1,000 | 3,500 | 2,250 | 1,000 | 2,500 |
(b) Average daily sales
\[\text{Total sales}=₦1,750+₦1,000+₦3,500+₦2,250+₦1,000+₦2,500=₦12,000\]
\[\text{Average daily sales}=\frac{₦12,000}{6}=₦2,000\]
Therefore, the average daily sales for the week is ₦2,000.
