the manager of a cafeteria kept track of the number of each type of lunch sold in october and made this table. which graph correctly and completely represents the data in the table?
lunches sold in october
lunch\tnumber sold
deli sandwich\t300
hamburger\t500
pasta plate\t400
pizza\t650
soup combo\t150

Explanation:

Step1: Analyze the data values

We have Deli Sandwich - 300, Hamburger - 500, Pasta Plate - 400, Pizza - 650, Soup Combo - 150.

Step2: Check each graph

• First graph has incorrect intervals and does not represent individual - item data properly.
• Second graph: Deli Sandwich bar is around 300, Hamburger bar is around 500, Pasta Plate bar is around 400, Pizza bar is around 650, and Soup Combo bar is around 150. This graph correctly represents the data.
• Third graph has incorrect heights for the bars compared to the data values.
• Fourth graph is a pictograph but the number of symbols for each item does not match the data (e.g., if each symbol represents 10 lunches, the counts are off).

Answer:

The second graph (the bar - graph with correct heights for each lunch type)
