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?

Respuesta :

Answer:

42 + 2n  ≥ 80

Step-by-step explanation:

Given,

Naomi's earnings for one day = $ 42,

Also, she earns extra $2 for each CD she sells,

Thus, the extra earning for n CDs = 2n dollars,

So, her total earning for a day if she sells n CDs = ( 42 + 2n ) dollars,

If Naomi wants to earn at least $80 per day,

Her total earning ≥ 80 dollars,

⇒ 42 + 2n  ≥ 80

Which is the required inequality.
