Question

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?

The table is entitled Lunches Sold in October. It shows Lunch and Number Sold. Deli Sandwich, 300. Hamburger, 500. Pasta Plate, 400. Pizza, 650. Soup Combo, 150.


A pictograph is entitled Lunches Sold in October. It shows lunches and pictures of rectangles. A key shows one rectangle equals 10 lunches. Deli Sandwich, 3 rectangles. Hamburger, 5 rectangles. Pasta Plate, 4 rectangles. Pizza, 6 rectangles and 1 half rectangle. Soup Combo, 1 rectangle and 1 half rectangle.


A bar graph is entitled Lunches Sold in October. It shows Lunch and Number Sold. Deli Sandwich, midway between 100 and 200. Hamburger, 300. Pasta Plate, 400. Pizza, 500. Soup Combo, midway between 600 and 700.

A bar graph is entitled Lunches Sold in October. It shows Lunches Sold in October and Types of Lunches. 101-300, 2. 301-500, 2. 501-700, 1.

Answer 1

The fourth bar graph. It shows Deli = 300, Hamburger = 500, Pasta = 400, Pizza ≈ 650 (midway 600–700), and Soup ≈ 150 (midway 100–200), which exactly matches the table. The other graphs use the wrong scale, swap values, or aggregate the data so they are not a correct and complete representation.
