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 number sold
deli sandwich 300
hamburger 500
pasta plate 400
pizza 650
soup combo 150

Explanation:

To determine the correct graph, we analyze the data from the table:

• Deli Sandwich: 300
• Hamburger: 500
• Pasta Plate: 400
• Pizza: 650
• Soup Combo: 150

Step 1: Analyze the first graph (categorical ranges)

This graph uses ranges (101–300, 301–600, 501–700) for the x - axis. The counts don’t match the actual numbers (e.g., Soup Combo is 150, which should be in 101–300, but the graph’s bars don’t align with the exact counts).

Step 2: Analyze the second graph (pictograph)

The key is 1 square = 10 lunches. Let’s check:

• Deli Sandwich: \( 300 \div 10 = 30 \) squares (but the graph shows far fewer).
• Hamburger: \( 500 \div 10 = 50 \) squares (also incorrect). So this is wrong.

Step 3: Analyze the third bar graph

We check the heights of the bars against the number sold:

• Deli Sandwich: ~150 (incorrect, should be 300).
• Hamburger: ~300 (incorrect, should be 500). So this is wrong.

Step 4: Analyze the fourth bar graph

Check each bar:

• Deli Sandwich: ~300 (matches 300).
• Hamburger: ~500 (matches 500).
• Pasta Plate: ~400 (matches 400).
• Pizza: ~650 (matches 650).
• Soup Combo: ~150 (matches 150).

Answer:

The fourth bar graph (the last one with "Number Sold" on the y - axis and lunch types on the x - axis, showing correct bar heights for each lunch type) correctly represents the data.
