Answer:
Jennifer made more money than her mother.
Explanation:
Today, Jennifer earns $50000 at her first job.
Her mom used to make $15,000 at her first job in 1975.
The CPI today is 231 and the CPI in 1975 was 82.
Purchasing power of Jennifer's mother currently
[tex]= \frac{15,000}{82}\ \times\ 231[/tex]
= $42,256
Jennifer's purchasing power in 1975
[tex]= \frac{50,000}{231}\ \times\ 82[/tex]
= $17,748
Jennifer is currently making more than what her mother could have made if she started working today. Also, she would have earned more than her mother if she had started working in 1975.
