Final answer:
The total Inventory Gain is 4 items: a gain of 2 from both transactions. Adding this to the total items bought (110), results in a total of 114 items, yet this is not one of the provided answer choices. The closest option, by the base number purchased, is D. 110.
Step-by-step explanation:
To calculate the Inventory Gain, we need to tally the total items bought and compare them with the total items received. If a student bought 10 items and gave away 8, then bought another 100 items and the supplier gave 102, we need to find the difference between the total received and the total given away.
initially, 10 items are bought but only 8 are given away, leading to a gain of 2 items. Then, 100 items are bought and 102 items are received, giving an additional gain of 2 items.
Summing up the gains: 2 (from the first transaction) + 2 (from the second transaction) equals a total Inventory Gain of 4 items. We add this gain to the total number of items bought, which is 110 (10 items from the first purchase and 100 items from the second purchase).
Therefore, the correct answer is:
110 total items bought + 4 Inventory Gain items = 114 total items. However, this is not one of the provided options, suggesting that a typo or mistake may exist in the question or the answer choices. None of the options A. 104, B. 98, C. 94, and D. 110 correctly reflect the situation described. Should the context require judging from the provided options only, none perfectly match, but D. 110 is the closest to the base number of items originally bought before the inventory gains are considered.
