The friend who makes lemonade with the strongest lemon flavor can be determined by comparing the ratios of lemon juice to the total amount of lemonade used in their recipes. To do this, we can use unit rates. Unit rates help us compare quantities by considering one unit of each quantity. In this case, we can compare the amount of lemon juice used in each friend's recipe by considering the ratio of lemon juice to the total amount of lemonade in each recipe. Let's take a look at the ratios given in the table: - Friend 1: 1:4 - Friend 2: 1:3 - Friend 3: 1:2 To determine the unit rate for each friend, we need to find the amount of lemon juice used for one unit of lemonade. We can do this by dividing the amount of lemon juice by the total amount of lemonade in each ratio. - For Friend 1: 1 lemon juice / 4 total lemonade = 1/4 or 0.25 - For Friend 2: 1 lemon juice / 3 total lemonade = 1/3 or 0.33 - For Friend 3: 1 lemon juice / 2 total lemonade = 1/2 or 0.5 Comparing the unit rates, we can see that Friend 1 has the lowest unit rate of 0.25, which means they use the highest concentration of lemon juice in their lemonade recipe. Therefore, Friend 1 makes lemonade with the strongest lemon flavor. In summary, to determine which friend makes lemonade with the strongest lemon flavor, we compare the unit rates of lemon juice to total lemonade in each friend's recipe. The friend with the lowest unit rate has the strongest lemon flavor
