Answer:
350 lightbulbs
Step-by-step explanation:
First find the number of batches made. 
20,000 divided by 400 = 50
This means that there are 50 batches in which 7 light bulbs will be selected at random to be inspected. 
We can multiply the number of batches to the lightbulbs being inspected. 
50 times 7 = 350
Therefore, 350 lightbulbs will be inspected. 
Please tell me if I am incorrect :)
