Final answer:
Chiko's purchase price was $1468.5.
Step-by-step explanation:
To find Chiko's purchase price, we need to calculate the total cost of the shares. We can start by multiplying the number of shares purchased by the purchase price per share: 75 shares * $19.58/share = $1468.5
Next, we need to subtract the dividends received during the year from the total cost: $1468.5 - $73.42 = $1395.08
Finally, to find the purchase price, we need to subtract the end of year valuation from the remaining cost: $1395.08 - ($22.14 * 75) = $1468.5
Therefore, Chiko's purchase price was $1468.5, option (a).
