Answer 1

Step-by-step explanation:

Given The graph shows the relationship between the total cost and the number of erasers bought at the student store. Which statement is true?

So we have in the graph number of erasers on the x axis and the total cost on the y axis.

According to the graph each eraser will cost $ 0.5

So for total 9 erasers the cost is 4.5

Now one eraser will cost $ 0.5

Therefore 7 erasers will cost 0.5 x 7 = $ 3.5

Also we can do it as  

      9 erasers will cost $ 4.5

     7 erasers will cost 7 x 4.5 / 9

                                 = $ 3.5
