Question

Jalen lost 12 pounds in the first 3 weeks of his diet. After this point, his weight loss rate slowed by half. If he lost a total of 84 pounds, how many weeks did it take him? lbs 100​

Answer 1

Answer:

Step-by-step explanation:

Jalen lost 12 pounds in the first 3 weeks

12/3=4 per week

than the weight loss slowed by half, meaning he lost 6 pounds in 3 weeks

6/3=2 per week

84-12=72 to loose after 3 weeks

72/2=36 weeks

to loose 84 pounds you need 3+36=39 weeks

for 100 lbs

100-12=88

88/2=44

44+12=56 weeks
