Answer:
The correct option is D) Seven eraser cost $3.50
Step-by-step explanation:
Consider the provided graph.
The graph shows the relationship between the total cost and the number of erasers bought at the student store.
Here the x-axis represents the number of erasers bought and the y-axis represents the total cost.
Now consider the provided options.
Options (A) Each eraser cost $1.00
This option is incorrect because when x = 1 the value of y = 0.5, that means the cost of each eraser is $0.5
Options (B) Each eraser cost $1.50
This option is incorrect as the cost of each eraser is $0.5
Options (C) Three eraser cost $6
This option is incorrect because when x = 3 the value of y = 1.5, that means the cost of 3 eraser is $1.5
Options (D) Seven eraser cost $3.50
This option is correct because when x = 7 the value of y = 3.5, that means the cost of 7 eraser is $3.5
