Please solve the following question given the information

Company A:

Product Selling Price = $40

Variable Costs = $10 per/unit

Fixed Costs = $12,000

To make a profit of $6,000, the number of units sold were 600 units and $24,000 dollars sales.

If the company could spend 4000 dollars on advertising, which results in increasing the selling price by $10, how many units would they need to sell to break even?
