You work for a marketing firm that has just landed a contract with Run-of-the-Mills to help them promote three of their products: splishy splashies, frizzles, and cannies. All of these products have been on the market for some time, but, to entice better sales, Run-of-the-Mills wants to try a new advertisement that will market two of the products that consumers will likely consume together. As a former economics student, you know that complements are typically consumed together while substitutes can take the place of other goods. Run-of-the-Mills provides your marketing firm with the following data: When the price of splishy splashies decreases by 5%, the quantity of frizzles sold decreases by 4% and the quantity of cannies sold increases by 6%. Your job is to use the cross-price elasticity between splishy splashies and the other goods to determine which goods your marketing firm should advertise together.

Complete the first column of the following table by computing the cross-price elasticity between splishy splashies and flopsicles, and then between splishy splashies and kipples.
