Sophia works in a clothing store and earns $40 per day. She earns an extra $5 for each outfit she sells. If Sophia wants to earn at least $70 per day, which inequality shows the minimum number of outfits, n, that she should sell?
40 + 5n ≤ 70, so n ≤ 6
40 + 5n ≥ 70, so n ≥ 25
40 + 5n ≤ 70, so n ≤ 25
40 + 5n ≥ 70, so n ≥ 6
