111% increase
Equation:
3.49x = 3.89
x = 11%
Using Lagrange multipliers, we have the Lagrangian
with partial derivatives (set equal to 0)
Substituting the first three equations into the fourth allows us to solve for
:
For each possible value of
, we get two corresponding critical points at
.
At these points, respectively, we get a maximum value of
and a minimum value of
.
Answer: The percent of the estimated time is the actual time is about 14%.
Step-by-step explanation:
As per given,
Actual time of completing the job =
Estimated time for completing the job =
The percentage error is given by:-
The percent of the estimated time is the actual time is about 14%.
