The following chart shows the prices for five companies on Jan $1^{st}$ of $2022,2023$ and $2024$:

b$)$ Now suppose that, on Jan $1,2023,$ Akita Automobile was removed from the index,

and Dalmatian Designs was added to the index. Calculate the new divisor.

c$)$ Now $($after the replacement in part b$),$ calculate the value of the $K9$ index in $2024.$

Jan $1,2022$ to Jan $1,2023)?$
