Final answer:
The total amount removed from Joshua's estate in 2022 as a result of the gift in 2021 is $20,200.
Step-by-step explanation:
To calculate the total amount removed from Joshua's estate, we need to find the difference in the value of the XYZ shares between 2022 and 2021.
In 2021, Joshua gave $5,900 worth of XYZ stock to his son. In 2022, the shares are worth $26,100.
