How many people? • 8% of the people in the U.S. • 310 million people live in the U.S.

310 Million

What is 8% of 310

Million? 8%

310 Million

= 100%

?

= 8%

By estimating, I know that

31 million is 10% of 310

million.

310 Million

= 100%

?

= 8%

310,000,000 x .08 = 24.8 million

310 Million

= 100%

24.8 million

= 8%

310,000,000 x .08 = 24.8 million

310 Million

How many people per

store? 12,800

24,800,000 /
