Naomi works in a music shop and earns $42 per day. She earns an extra $2 for each CD she sells. If Naomi wants to earn at least $80 per day, which inequality shows the minimum number of CDs, n, that she should sell? (5 points) Group of answer choices 42 + 2n ≥ 80, so n ≥ 36 42 + 2n ≥ 80, so n ≥ 19 42 + 2n ≤ 80, so n ≤ 19 42 + 2n ≤ 80, so n ≤ 36
