Can you please explain how to do this?? When I solved it, I got a as my answer but I'm not sure if its correct.

Sunland Company produces flash drives for computers, which it sells for $20 each. Each flash drive costs $10 of variable costs to make. During April, 1200 drives were sold. Fixed costs for April were $4 per unit for a total of $4800 for the month. If variable costs decrease by 20%, what happens to the break-even level of units per month for Sunland Company? 0 It is 20% higher than the original break-even point. It decreases about 80 units. It decreases about 96 units. O It depends on the number of units the company expects to produce and sell
