Amy earns $300 per week working at a shoe store. She also earns $4 for each pair of shoes she sells. This week, she wants to earn more than $500. If p is the number of pairs of shoes Amy sells, which inequality represents this situation and what quantities are true for p?
4p + 300 > 500, where p > 50
4p + 300 > 500, where p > 200
300p + 4 > 500, where p > 50
300p + 4 > 500, where p > 200
