Final answer:
Devin's total return on his investment in CDEF stock was $1692, which includes a capital gain of $1442 from the sale of the stock and $250 from dividends received.
Step-by-step explanation:
To calculate Devin's total return on his investment in CDEF stock, we need to consider both the capital gain from the sale of the stock and the dividends received during the period he held the stock.
Devin bought 100 shares at $30 each, so the initial investment was 100 x $30 = $3000. He paid a commission of $29 when buying, so total purchase cost is $3000 + $29 = $3029.
He sold the 100 shares at $45 each for a total of 100 x $45 = $4500. He paid another commission of $29 when selling, so the total amount received from the sale is $4500 - $29 = $4471.
The capital gain is therefore $4471 (sale proceeds) - $3029 (cost) = $1442.
Devin also earned dividends of $2.50 per share on his 100 shares, which totals to 100 x $2.50 = $250.
Adding the capital gain and the dividends gives us Devin's total return: $1442 (capital gain) + $250 (dividends) = $1692.
