Answer:
The company must sell 10,00 products to break even
Explanation:
If you use the approached suggested in the question,  you can solve for break even quantity by setting revenue to equal cost 
R = C => 9x = 50,000 + 4x => 5x = 50,000 => x =10,000
<u>Double check: </u>
10,000 products sold as $9 would fetch $90,000 in revenue
Producing 10,000 products would incur 50,000 + 4 * 10,000 = $90,000 in total costs
=>The solution is correct
