Gabriela and her mother sell sweatshirts (s) for $25 and t-shirts (t) for $10.50. They are positive more than 10 T-shirts and at least 2 sweatshirts will be sold this weekend. If they want to make at least $400, which system could be used to determine the possible numbers of sweatshirts (s) and T-shirts (t) they would need to sell?

• s ≥ 2 t ≥ 10 25s + 10.5t ≥ 400

• s ≥ 2 t > 10 25s + 10.5t ≥ 400

• s > 10 t ≥ 2 10.5s + 25t ≥ 400

• s ≥ 2 t > 10 10.5s + 25t ≥ 400
