Final answer:
To calculate the equivalent annual saving from the purchase, divide the cost of the glueball by the number of years it will be used.
Step-by-step explanation:
To calculate the equivalent annual saving from the purchase, we need to determine the depreciation amount and the number of years the glueball will be used.
Since Gluon can depreciate 100% of the investment immediately, the depreciation amount is equal to the cost of the glueball.
Let's say the cost is $80,000. If the glueball is expected to be used for 5 years, the equivalent annual saving would be $80,000 / 5 = $16,000. Therefore, the correct answer is $16,000.
