Answer: $644
Explanation:
From the question, we are informed that Michelle and Patrick are in the 28% marginal tax bracket and that they bought 100 shares of djn stock at $45 per share and sold them 4 years later in 2015 at $22 per share.
To get the amount by which their loss reduce their taxes in the year when they sold the stock goes thus:
= 28% × [($45 × 100) - ($22 × 100)]
= 28% × ($4500 - $2200)
= 28% × $2300
= 0.28 × $2300
= $644
