Answer: You would need to sell $66,667 worth of electronics.
Explanation:
We can use equations:
Option A - 20,000 + 0.12x
Option B - 26,000 + 0.03x
If we set them equal to each other, we can find the x value at which the electronics sold give us equal income
20000+0.12x = 26000+0.03x
0.9x = 6,000
x = 66,666.67
