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.
