1. Define the variables and write the equations for total cost and revenue:

\text{Total cost} = 20x + 2000

\text{Revenue} = 30x

2. Set the profit equation to zero and solve for \( x \):

30x - (20x + 2000) = 0

30x - 20x - 2000 = 0

10x - 2000 = 0

10x = 2000

x = 200

3. Therefore, the number of radios needed to earn zero profit is:

200

2. Set the profit equation to zero and solve for \( x \):

3. Therefore, the number of radios needed to earn zero profit is:
