Answer:
He should sell his CD's for $2.
Step-by-step explanation:
Each crate contains 60 blank CD’s and each crate cost $35.
This means that he will pay $35 for 60 CD's.
How much should he sell his CD’s to make a profit of $85?
He will sell each of the 60 CD's for x, which means that his earnings will be of 60x.
Profit: Earnings - Cost = 60x - 35
To make a profit of $85
![60x - 35 = 85](https://tex.z-dn.net/?f=60x%20-%2035%20%3D%2085)
![60x = 120](https://tex.z-dn.net/?f=60x%20%3D%20120)
![x = \frac{120}{60}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B120%7D%7B60%7D)
![x = 2](https://tex.z-dn.net/?f=x%20%3D%202)
He should sell his CD's for $2.
