Final answer:
Brad's annual payment to Angie increased from $9,000 in 2019 to $18,000 in subsequent years, indicating an increase from 2019 to 2020.
Step-by-step explanation:
The question asks about the amount Brad was ordered to pay Angie for the year 2019 after their divorce was finalized. The statement in the question is that Brad was ordered to pay $18,000 a year, with $9,000 specified for 2019. The correct answer is B. Brad's annual payment increased from 2019 to 2020. This is because for the year 2019, he was required to pay $9,000, and for the subsequent years, the amount is $18,000 annually. This clearly indicates an increase in the annual payment from 2019 to 2020.
