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

She wants to make  $30+ along with her daily salary. Since every outfit she sells would be $5+, 
30 / 5 = 6. She would need to sell 6 outfits in order to make at least 70 per day.
All the rest of that weird is confusing, so if it's a multiple choice look for 6. if not, put 6 as your answer.
Proof:

30 / 5 = 6
40 + 30 = 70.
and that should be it.
