The function defined by \( C(x) = 10x \) means that the cost \( C \) is directly proportional to the number of students \( x \) going on the field trip, with each student costing $10.
To find possible outputs, we can substitute various integer values of \( x \) (the number of students) into the function:
-
For \( x = 5 \):
\( C(5) = 10 \times 5 = 50 \) -
For \( x = 6 \):
\( C(6) = 10 \times 6 = 60 \) -
For \( x = 2 \):
\( C(2) = 10 \times 2 = 20 \) -
For \( x = 3.5 \):
\( C(3.5) = 10 \times 3.5 = 35 \) -
For \( x = 9.2 \):
\( C(9.2) = 10 \times 9.2 = 92 \)
From the provided options, the outputs that we found are:
- 60 (from \( x = 6 \))
- 20 (from \( x = 2 \))
- 35 (from \( x = 3.5 \))
- 92 (from \( x = 9.2 \))
So, the two possible outputs from your selections are:
- 60
- 20
If you can only select two, choose 60 and 20.
