Answer 1

2006 Pop. = 47.9 million 

 

Expected decrease = 4.8% = .048

 

Expected population =  47.9 million (1- .048) = 45.60 million

Answer 2

Hi Again Craig;

There are two techniques to calculate this...

47.9 million

4.8%

x=expected population in 050

4.8%=0.048

x=(47,900,000)-[47,900,000(0.048)]

x=47,900,000-2299200

x=45,600,800

 

home=45.6 million

or

100%-4.8%=95.2%=0.952

x=(0.952)(47,900,000)

x=45,600,800

x=45.6 million
