Thank you person for helping me I really do appreciate it :)

Option 4 is false

Step-by-step explanation:

By analyzing the graph we can see that the first three options are correct and the last one is incorrect

1. True. Point (0, 400) confirms the statement2. True. Point (1, 500) confirms the statement3. True. Point (2, 625) and other points confirm the statement4. False. Increase of 250 per year is not the case in early years of the graph. It would be a linear graph to have same number each year.

The discount is 8.70 . you dont tell us the percent of tax added so there is no way to find out, unless i'm not seeing anything. without tax its 37.70
