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? (1 point)
으
45 + 3n = 60, so n = 5
• 45 + 3n = 60, 50 n 25
• 45 + 3n =60, 50 n 2 12
45 + 3n = 60, so n = 12
To find the minimum number of CDs, n, that Ella should sell, we need to write an inequality that represents the given information.
Ella earns $45 per day and an extra $3 for each CD she sells. If she wants to earn at least $60 per day, we can write the inequality as:
45 + 3n ≥ 60
This inequality states that Ella's base earnings of $45 plus the earnings from selling n CDs (3n) is greater than or equal to $60.
So, the correct inequality is:
45 + 3n ≥ 60
Therefore, Ella should sell at least 5 CDs (n) in order to earn at least $60 per day.
