To find the outputs (range) for the function defined by \( C(x) = 10x \), where \( x \) is the number of students, we can calculate the output for various integer values of \( x \).
Since the cost is \( 10 \) dollars per student, we can multiply \( 10 \) by possible values of \( x \).
For instance:
- If \( x = 2 \), then \( C(2) = 10 \times 2 = 20 \)
- If \( x = 5 \), then \( C(5) = 10 \times 5 = 50 \)
- If \( x = 6 \), then \( C(6) = 10 \times 6 = 60 \)
- If \( x = 9 \), then \( C(9) = 10 \times 9 = 90 \)
From the provided options, we see that:
- 20 (from \( C(2) \))
- 60 (from \( C(6) \))
Thus, the two possible outputs from the options given are 20 and 60.
