a. 72,400
b. 71,200
c. 71,500
d. 71,980

Answer :

Final answer:

The three-year weighted moving average for Year 5 is 71,980, calculated using the given demand values and weights.

So the correct option is d. 71,980

Explanation:

The three-year weighted moving average for Year 5 is calculated by multiplying the demand values of the last three years by their respective weights and then summing them up.

Weighted moving average = (71,200 x 0.4) + (75,500 x 0.2) + (71,000 x 0.4) = 28,480 + 15,100 + 28,400 = 71,980.

Therefore, the answer is d. 71,980.
