A Retail Store Sells a Popular Cosmetic Called Anya, and the Store

A retail store sells a popular cosmetic called Anya, and the store manager is given $100,000 by the corporate office to improve store performance any way she thinks best. The "base case" information is a price of $50 per bottle, a contribution margin of 0.50, a customer defection rate of 25%, and a repurchase frequency of 3 times a year. If these improvement funds could be used to either increase the contribution margin to 0.58 or reduce the customer defection rate to 15% or increase the repurchase frequency to 4 times per year, what is the best way to spend these funds? (Assume all other variables remain at the base case level for each improvement option.)
You may want to use the table below to help organize your computations and answer. $\begin{array}{|c|c|c|c|c|c|}\hline&&\text { Contribution }&\text { Repurchase }\\\text { Option } & \underline{\text { Price }}&\text { Margin }&\text { Frequency }& \text { Defection Rate } &\underline{\text { VLC in } \$}\\\hline \begin{array}{l}\text { Base } \\\text { case }\end{array} & \$ 50 & 0.50 & 3 & 25 \% \\\hline \text { (a) } & \$ 50 & 0.58 & 3 & 25 \% & \\\hline \text { (b) } & \$ 50 & 0.50 & 3 & 15 \% & \\\hline \text { (c) } & \$ 50 & 0.50 & 4 & 25 \% & \\\hline\end{array}$ Note: BLC is 1/0.25 = 4 years and 1/0.15 = 6.67 years.
