Profit will be achieved when the money earned is greater than the money spent so,
336 + (n*12) = n*28 any subsequent units sold would result in profit
336 = 28n - 12n
336 = 16n
=> n = 336/16 = 21
21 units must be sold to draw even any more would result in profit
131.818182% and can round to 131.82
The answer is 360 because if u do this 20×36 and the 1/2 it u get this 360 20×36 is 720 and then 2÷720 u get 360
When in doubt C it out man, cant answer it if there aren't any problems to solve
