To find a viable solution, we need to ensure that the total number of cheerleaders selected for both squads adds up to 12 and that the number of cheerleaders for each squad is non-negative.
Let's analyze the options:
- 15 varsity cheerleaders and -3 junior varsity cheerleaders: This is not viable due to the negative number of junior varsity cheerleaders.
- 8 varsity cheerleaders and 8 junior varsity cheerleaders: This totals to 16, which exceeds 12, so it’s not viable.
- 8 varsity cheerleaders and 4 junior varsity cheerleaders: This totals to 12, which is viable.
- 0 varsity cheerleaders and 12 junior varsity cheerleaders: This totals to 12 as well, making it viable.
The viable solutions are:
- 8 varsity cheerleaders and 4 junior varsity cheerleaders
- 0 varsity cheerleaders and 12 junior varsity cheerleaders
Therefore, the responses "8 varsity cheerleaders and 4 junior varsity cheerleaders" and "0 varsity cheerleaders and 12 junior varsity cheerleaders" are both viable solutions.
