Answer 1

Answer: 2.2464 × 10^8

Step-by-step explanation:

Percentage of obese Americans in 2011 - 2012 = 35%

Percentage of Americans who are adult = 72%

United States population estimate = 312 million

Adult = age 20 and above

Number of adult Americans (age 20 and above) :

72% of the total united states estimated population

72% of 312,000,000

72/100 × 312,000,000

0.72 × 312,000,000

= 224,640,000

Hence, estimated Adult American population (age 20 and above) = 224,640,000

2.2464 × 10^8
