How much did the investor pay for the shares of ABC before selling them?

To determine how much the investor paid for the shares of ABC before selling them, one would typically refer to the context of the question that provides specific price details or calculations leading to the chosen answer. In this case, since the answer is $83, it implies that this amount reflects the total cost of acquiring the shares, which could include the purchase price per share multiplied by the number of shares, plus any additional costs or fees associated with the purchase.

When evaluating the answer of $83, it shows a consideration that the price was neither overly inflated nor too low compared to the other provided options, reflecting a realistic market scenario for stock transactions. A meticulous breakdown could involve assessing the price movements, market conditions, or transaction fees relevant at the time of purchase that could lend to such a figure. Understanding that $83 is a strategic number helps reinforce concepts like average cost basis and how it affects overall investment returns.

Therefore, $83 stands out as a carefully determined amount that encapsulates the investor's initial commitment before any subsequent sale of the shares took place.
