Question

At a local thrift shop, Loren bought 2 plates for $2.50. Dana bought 6 plates for $7.50. Shane bought 7 plates for $8.75. PART B: Select all the points that could be on a graph of the relationship between the number of plates bought and the cost of the plates. ​

Answer 1

The points that could be on the graph of the relationship between the number of plates bought and the cost of the plates are (2, $2.50), (6, $7.50), and (7, $8.75).

Step-by-step explanation:

The relationship between the number of plates bought and the cost of the plates can be represented on a graph. The x-axis represents the number of plates bought, and the y-axis represents the cost of the plates. To determine the points that could be on the graph, we need to examine the given information.

Loren bought 2 plates for $2.50, Dana bought 6 plates for $7.50, and Shane bought 7 plates for $8.75. We can calculate the cost per plate by dividing the total cost by the number of plates bought.

For Loren: $2.50 ÷ 2 plates = $1.25 per plate

For Dana: $7.50 ÷ 6 plates = $1.25 per plate

For Shane: $8.75 ÷ 7 plates ≈ $1.25 per plate

From these calculations, we can see that the cost per plate for all three purchases is the same, $1.25. Therefore, the points (2, $2.50), (6, $7.50), and (7, $8.75) could all be on the graph representing the relationship between the number of plates bought and the cost of the plates.
