Answer:
[tex]A\text{ :261}[/tex]
Explanation:
Here, we want to calculate the CPI for the cost of the suit
To do this,we use the weighted average method
What we will do here is to divide the past price by the current price and convert the value to a percentage
Mathematically, we have this as:
[tex]\frac{\text{Present cost}}{\text{Cost in 1967}}\text{ }\times\text{ 100 \%}[/tex]Substituting the values, we have:
[tex]\frac{235}{90}\text{ }\times\text{ 100 = 261}[/tex]
