Final answer:
To assess the system of equations, we need to set up the equations based on Brendan's situation. The primary topic of this question is solving systems of equations.
Step-by-step explanation:
To assess the system of equations, we need to set up the equations based on Brendan's situation. Let's assume x represents the number of hours Brendan works as a teaching assistant and y represents the number of hours he works as a dishwasher.
We can then set up the equations:
18x + 12y ≥ 520 (equation 1, to cover his expenses)
x + y ≤ 15 (equation 2, because he can only work a maximum of 15 hours per week)
These two equations represent Brendan's earning potential and work hours. By solving these equations, we can determine the feasible solutions for Brendan.
