To determine the appropriate inequality that shows the range of Dorian's earnings from walking dogs, we need to consider both the minimum and maximum constraints.
1. **Minimum Earnings**: Dorian cannot earn negative money from walking dogs. So, the minimum earnings are $0. Thus, we have \( f(w) \geq 0 \).
2. **Maximum Earnings**: We need to know how many dogs he can walk to determine the upper limit of his earnings. If we assume that the maximum he can earn is $1,050, we set up \( f(w) \leq 1,050 \).
Putting these together, we can write the range of his earnings as \( 0 \leq f(w) \leq 1,050 \).
Thus, the correct inequality that shows the range of Dorian's earnings is:
**0 ≤ f(w) ≤ 1,050**.
