Question

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

Answer 1

20 extra Cds is the answer to the problem but all the inequalitys are so much together that I can not read sorry
