Ryan has 1,500 yards of yarn. He wants to knit at least 2 scarves and at least 3 hats. Each scarf requires 300 yards of yarn, and each hat requires 120 yards of yarn. If s represents the number of scarves and h represents the number of hats, which of the following systems of inequalities represents this situation? s+h≤1,500s≥2h≥3

2s+3h≤1,500s≥2h≥3

2s+3h≤1,500s≥300h≥120

300s+120h≤1,500s≥2h≥3
