Suppose that you run a grocery store and are trying to decide whether you should place two products next to each other or not to possibly enhance sales. You have your data analyst calculate some numbers and you discover that the two products (call them product ``A'' and product ``B'') are sold together across 0.30 of the total transactions. Product A is sold across 0.70 of the total transactions. And Product B is sold across 0.85 of the total transactions. Calculate the Lift between the two products. (You can enter a number up to two decimal places. Example 1.55 or 0.55)
