Answer:
400 CDs
Explanation:
The equation y=5x+0 represents that the profit increases linearly with the number of CDs sold, the slope of 5 indicates that for every 1 CD sold, the profit increases by $5.
The y-intercept of 0 indicates that there is no profit when no CDs are sold.
To earn a minimum profit of $2000, we can set up the following equation:
2000 = 5x + 0
5x = 2000
Divide both sides by 5.

x = 400
Therefore, we need to sell 400 CDs to earn a minimum profit of $2000.
