Answer:

The answer is 1.25$

Explanation:

To identify the graph and unit price that represent the cost of the apples, we can create a graph where the x-axis represents the weight of apples in pounds and the y-axis represents the cost in dollars. Each friend's purchase can be represented as a point on the graph, and the unit price can be determined from the slope of the line that passes through these points.

First, let's calculate the unit price for each friend:

Logan:

Unit price = Total cost / Weight = $5.00 / 4 pounds = $1.25 per pound

Point: (4, $5.00)

Lin:

Unit price = Total cost / Weight = $7.50 / 6 pounds = $1.25 per pound

Point: (6, $7.50)

Chita:

Unit price = Total cost / Weight = $2.50 / 2 pounds = $1.25 per pound

Point: (2, $2.50)

All three friends have bought apples at the same unit price, $1.25 per pound. This means the graph representing their purchases will be a straight line passing through the points (4, $5.00), (6, $7.50), and (2, $2.50).

In this graph, the x-axis represents the weight of apples in pounds, and the y-axis represents the cost in dollars. The unit price, $1.25 per pound, is represented by the slope of the line passing through these points.
