Answer:
The first answer is the one you want
Step-by-step explanation:
The rate of change is the slope. Here it is represented by the dollar value/number of tickets sold. This will give you the 1:1 ratio, meaning it will give you the number of dollars generated by the sale of 1 ticket. That's what rate of change is.
Use the slope formula and 2 points on the table. I chose the points (225, 250) and (200, 0):
[tex]\frac{0-250}{200-225} =\frac{-250}{-25} =10[/tex]
That translates to $10 per ticket.
