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
B as if you plug the co-ordinates into the equation and it equals 10: (3x4)-2= 12-2 =10
A doesn't work as the answer is 20
C doesn't work as the answer is 14
D doesn't work as the answer is -20
