Answer:
$0.32 per share
Explanation:
For computing the lower price per share first we have to find out the average cost per share which is shown below:
1 $400 ÷ $13 = 30.769
2 $400 ÷ $10 = 40.000
3 $400 ÷ $8 = 50.000
4 $400 ÷ $9 = 44.444
$1,600 = 165.213 shares
Average cost per share = Total cost ÷ total number of shares
= $1,600 ÷ $165.213 shares
= $9.68 per share
And, the average price per share is
= ($13 + $10 + $8 + $9) ÷ 4
= $10 per share
So, the lower value is
= $10 per share - $9.68 per share
= $0.32 per share
