Ella works in a music shop and earns $45 per day. She earns an extra $3 for each CD she sells. If Ella wants to earn at least $60 per day, which inequality shows the minimum number of CDs, n, that she should sell? 45 + 3n ≤ 60, so n ≤ 5 45 + 3n ≥ 60, so n ≥ 5 45 + 3n ≥ 60, so n ≥ 12 45 + 3n ≤ 60, so n ≤ 12
