Final answer:
Jalen lost 12 pounds in the first 3 weeks, then his rate slowed by half. After losing 72 pounds at this slower rate, the solution is that it took him a total of 39 weeks.
Explanation:
The subject of this question is mathematics, specifically involving rate and time calculations. Jalen lost 12 pounds in the first 3 weeks. After this, his weight loss rate dropped by half. Before, he was losing 12 pounds in 3 weeks, which means he was losing 4 pounds per week (12/3=4). If his rate slows by half, he is now losing 2 pounds per week. If he lost a total of 84 pounds, and we know that 12 of those were lost in the first 3 weeks, that means he lost 72 pounds at the slower pace of 2 pounds per week, which would take him 36 weeks (72/2=36). Therefore, it took him a total of 3 weeks + 36 weeks = 39 weeks.
