Given:
The cost of the coat is $175.5 when CPI was 205
Let the cost is x when when CPI was 175
So, using the ratio and proportional to find x:
so,
[tex]\begin{gathered} \frac{x}{175.5}=\frac{175}{205} \\ \\ x=175.5\cdot\frac{175}{205}=149.82 \end{gathered}[/tex]
So, 5 years earlier, the cost will be $149.82
The answer is option A) $149.82
