Answer: See attached.
Explanation:
First, we will find the unit rate by dividing.
30 rings / $12 = 2.5 rings per dollar
Then, we can fill out the other values using this unit rate.
2 dollars * 2.5 rings per dollar = 5 rings
45 tosses / 2.5 rings per dollar = 18 rings
Lastly, we will use these two equivalent ratios we found above to fill out the table and then plot the points. See attached.
