Rice. 120
Yam. 100
Beans. 140
Vegetable 140
Meat. 180
Sugar. 40
Palm oil. 60

Display using a pie chart

Answer 1

To create a pie chart of the weekly expenditures on food items, calculate the total expenditure, determine each item's percentage of the total, convert percentages to angles, and draw the pie chart with each angle representing each food item expenditure.

Step-by-step explanation:

To display the weekly expenditure of a housewife on food items using a pie chart, we first need to calculate the total expenditure and then figure out what percentage of the total each item represents. We'll then be able to represent each item as a slice of the pie chart that corresponds to its percentage.

1. Add up the expenditure for each item to find the total: 120 (Rice) + 100 (Yam) + 140 (Beans) + 140 (Vegetable) + 180 (Meat) + 40 (Sugar) + 60 (Palm oil) = 780.
2. Calculate the percentage each item represents of the total expenditure. For example, for rice: (120/780) * 100 = 15.38%.
3. Convert these percentages into angles for the pie chart, knowing that a pie chart represents 100% as a full circle, which is 360 degrees. Thus, Rice would take up 15.38% of 360 degrees, which is around 55.36 degrees.
4. Repeat step 3 for each item to find all the angles.
5. Draw the pie chart using these determined angles, ensuring each slice represents the corresponding food item and its expense percentage.

The above calculations demonstrate how to convert a table of expenditures into a pie chart for visual representation, which could provide insights similar to the data on consumption choices of Americans from the Consumer Expenditure Survey.
