Answer:
$2,000
Explanation:
Based on the information provided within the question it can be said that Alex's amount of recognized gain was that of $2,000. This is because his car that he wrecked is valued at $20,000. Since he got $22,000 it means he made a gain of $2,000 regardless of how much he spends on a new car. Since he can decide to buy whatever car he wants, he can spend more or less than the money he received.
