A restaurant manager can spend at most $400 a day for operating costs and payroll. It costs $80 each day to operate the restaurant and $40 dollars a day for each employee. Use the following inequality to determine how many employees the manager can afford for the day, at most: 40x + 80 ≤ 400 x ≥ 8 x ≥ 12 x ≤ 8 x ≤ 12
