Gabriela is the manager of a print shop. She needs to schedule employees to work no more than 300 person-hours per week. She has one 20 hour a week part-time employee. Each full-time employee works 40 hours per week. Which inequality will determine f, the number of full-time employees Gabriela can schedule to remain under the 300 person-hour per week limit?

• $20\ +\ 40f\ \le\ 300$

• $40\ +\ 20f\ \ge\ 300$

• $20\ +\ 40f\ \ge\ 300$

• $20f\ +\ 40\ <\ 300$
