Answer:
65,000 units
Step-by-step explanation:
Let the number of units be sold = x
Operating Income= Sales- Variable cost – Fixed Cost
Operating Income = 40x - 24x - 560,000
Operating Income = 16x - 560,000
Return on Investment = Operating Income / Net Operating Assets
16% = (16x - 560,000 )/ 3,000,000
480,000 = 16x - 560,000
16x = 480,000 + 560,000
16x = 1,040,000
x = 65,000 units
