To determine how much money Mini Motorbikes & More will make if they sell nine tickets based on the step function described, you would refer to the value on the y-axis at the point where the x-axis (Raffle Tickets Sold) equals nine.
If there is a visual representation of a step function with segments indicating different revenue levels according to the number of tickets sold, you would need to look for the value when the x-value is nine tickets.
From your provided options, the amounts are $100, $150, $200, and $250. Without the specific segments indicated in the graph, I cannot give an exact answer. However, if you remember the graph's values, select the corresponding amount that appears at the x-coordinate of 9.
If I had to make an educated guess based on common fundraising models, selling 9 tickets (which is 3 groups of 3 tickets) typically yields a revenue of around $150. But please check the graph's actual value at nine tickets to confirm.
