Answer:
444 thumb drives
Step-by-step explanation:
Break even is the point at which the proceeds are equal to the costs i.e. when Total cost = Total revenue. So using the equations provided, the breakeven point for Burnem Inc. will be 4x + 4884 = 15x, where x is number of thumb drives. We solve for x to get the answer:
4x + 4884 = 15x
4884 = 15x - 4x
4884 = 11x
x = 4884/11
x = 444 thumb drives
