Answer:
16 years
Step-by-step explanation:
Given
Required
Year they made loss
Start by differentiating P w.r.t t
Using first principle:
Equate to 0, in order to solve for t
So, we have:
Solve using quadratic equation
Where
a = 3, b = -48 and c = 20
So, we have:
Split:
or 
or 
or 
Approximate to whole numbers
or 
<em>Hence, they made loss 16 years after they took over</em>
