Question

a store is selling laptops for $800 each. use this information to fill in the table. then plot the ordered pairs given by the table.
number of laptops: 2, 6, 8
cost (in dollars): blank cells
graph with x-axis: number of laptops, y-axis: cost (in dollars)

Explanation:

Step1: Determine the cost per laptop

From the context, a laptop is sold for $800 each (assumed from typical problem structure if not fully visible, but the key is number of laptops times cost per laptop). Let's assume cost per laptop is $800 (since it's a common problem setup for such tables).

Step2: Calculate cost for 2 laptops

Cost = Number of laptops × Cost per laptop = \( 2 \times 800 = 1600 \) dollars.

Step3: Calculate cost for 6 laptops

Cost = \( 6 \times 800 = 4800 \) dollars.

Step4: Calculate cost for 8 laptops

Cost = \( 8 \times 800 = 6400 \) dollars.

Now, to plot the ordered pairs \((2, 1600)\), \((6, 4800)\), \((8, 6400)\) on the graph: find the x - value (number of laptops) on the x - axis and the corresponding y - value (cost in dollars) on the y - axis and mark the points.

Answer:

For the table:

• 2 laptops: Cost = 1600 dollars
• 6 laptops: Cost = 4800 dollars
• 8 laptops: Cost = 6400 dollars

For plotting: Mark the points (2, 1600), (6, 4800), (8, 6400) on the graph where x is number of laptops and y is cost (in dollars).
