The percent change in multifactor productivity if Fok can reduce the energy bill by $1,000 per day without cutting production or changing any other inputs

9.20% is the percent change in multifactor productivity if Fok can reduce the electricity bill by $1,000 per day without cut down production or changing any other inputs.

According to the question,

Reduce power by $950,

For analytical hierarchical productivity, we need to calculate the latest energy.

Total New Input(TNI):

Summation of all the inputs:

Initial efficiency factor: 0.0245 (as per question)

Hence, 9.20% is the percent change.

The answer is "2.45%".

Explanation:

The answer of option c:

Reduce power by 950 dollars:

In this question it will need to once again take the latest energy cost for analytical hierarchical productivity.  

→ Total Input  

Consumer rates  

Initial efficiency multi-factor= 0.0245
