Many, but not all people, use Cream Cheese on Bagels; therefore Bagets and Cream Cheese are complements.

Your research assistant forgot to label the results. You don't know whether $\backslash ($ W$,$ X $\backslash )$ or $\backslash ($ Y $\backslash )$ are Granola $($G$),$ Bagels $($B$)$ or Cream Cheese $($CC$)$ from the labels. Using the data in the below table of cross price elasticities, can you determine which of $\backslash ($ X$,$ Y $\backslash ),$ and $\backslash ($ Z $\backslash )$ are Granola $($G$),$ Bagels $($B$)$ and Cream Cheese $($CC$).$ Explain how you reached this conclusion.

A full answer will first state the formula for Cross Price Elasticity of Demand. Then use it to explain the answer. Cross Price Elasticity $($XED$)$ between the $3$ products:
