Final answer:
To convert Julia Roberts' salary into 2013 dollars, divide her salary by the CPI in 2003 and multiply it by the CPI in 2013. The adjusted salary is $31.82 million. To convert Sandra Bullock's salary into 2003 dollars, divide her salary by the CPI in 2013 and multiply it by the CPI in 2003. The adjusted salary is $55.01 million. Sandra Bullock had higher real earnings than Julia Roberts.
Step-by-step explanation:
To convert Julia Roberts' salary into 2013 dollars, we need to adjust for inflation. We can use the Consumer Price Index (CPI) to do this. The CPI in 2003 was 184, and in 2013 it was 233. To convert the salary, we can use the formula:
Adjusted Salary = (Salary in 2003 / CPI in 2003) * CPI in 2013
So, for Julia Roberts' salary:
Adjusted Salary = ($25 million / 184) * 233 = $31.82 million
To convert Sandra Bullock's salary into 2003 dollars, we can use the same formula but reverse the CPI values:
Adjusted Salary = (Salary in 2013 / CPI in 2013) * CPI in 2003
So, for Sandra Bullock's salary:
Adjusted Salary = ($70 million / 233) * 184 = $55.01 million
Comparing the adjusted salaries, we can see that Sandra Bullock had higher real earnings with $55.01 million compared to Julia Roberts' $31.82 million.
