To interpret the solution \( x > 120 \) in the context of the problem, we need to understand what \( x \) represents. In this case, \( x \) is the number of customers James serves. The solution suggests that James needs to serve more than 120 customers to earn more than $1,000.
Thus, the correct interpretation is:
C. James needs to serve more than 120 customers this week to meet his goal.
