The total amount invested in this case would be:
$50 x 1.75 = $87.50 (June 15)
$50 x 1.65 = $82.50 (July 15)
$50 x 2.00 = $100.00 (August 15)
So the total amount invested would be $87.50 + $82.50 + $100.00 = $270.00.
And the total number of shares purchased would be:
1.75 shares + 1.65 shares + 2.00 shares = 5.40 shares
Therefore, the average cost per share would be:
$270.00 / 5.40 shares = $50.00
So the average cost per share using dollar cost averaging would be $50.00.
