Question

data table organization
shopper time per item
lance and sarah began shopping at the same time.

• lance took 3.5 minutes to find each item.
• sarah took 3 minutes to find the first item, 5 minutes to find the second item, 4.5 minutes to find the third item, and 2.5 minutes to find the fourth item.

which of the data table arrangements correctly displays the time it took each shopper per item?

Explanation:

Step1: Analyze Lance's time per item

Lance took 3.5 minutes for each item. So for item 1, 2, 3, 4, his time per item is 3.5, 3.5, 3.5, 3.5.

Step2: Analyze Sarah's time per item

Sarah took 3 minutes (item 1), 5 minutes (item 2), 4.5 minutes (item 3), 2.5 minutes (item 4) per item.

Step3: Check Data Table 1

Data Table 1 shows cumulative times (e.g., Lance's second - column value 7 is \(3.5\times2\)) instead of time per item. So it's incorrect.

Step4: Check Data Table 2

Data Table 2 correctly shows Lance's time per item as 3.5 for each item and Sarah's time per item as 3, 5, 4.5, 2.5 for items 1 - 4 respectively.

Answer:

Data Table 2
