Number of Cups Needed to Make Punch A recipe is equivalent to another recipe if the ratios of their ingredients are the same. In this problem, we are exploring ratios and proportions in the context of making punch. You are in charge of mixing cups of punch for a party. The punch recipe requires apple juice, cranberry juice, and other ingredients. The ratio of cranberry juice to apple juice is given, and you need to determine the number of cups needed for each juice to make a total of 40 cups of punch. To find the ratio of cranberry juice to apple juice, we need to double the recipe. This means we need twice the amount of cranberry juice and the same amount of apple juice. So, if we start with 1 cup of cranberry juice, we will need 2 cups of apple juice. To triple the recipe, we need three times the amount of cranberry juice and the same amount of apple juice. So, if we start with 1 cup of cranberry juice, we will need 3 cups of apple juice. Now, let's compare the costs of two different brands of juice. We have a 16-ounce bottle of Shina juice and we want to compare its cost to another brand. To do this, we need to complete a table with the prices of each brand. Brand Price ($) Shina $5.84 Other $? To find the cost of the other brand, we need to use the given ratio. If the ratio of the prices is the same as the ratio of the quantities, we can set up a proportion and solve for the missing value. Abby can do 4 math problems in 6 minutes. How many math problems can she do in 10 minutes? To find the answer, we can set up a proportion: 4 math problems / 6 minutes = x math problems / 10 minutes To solve for x, we can cross-multiply and divide: 4 * 10 = 6 * x 40 = 6x x = 40 / 6 x ≈ 6.67 Abby can do approximately 6.67 math problems in 10 minutes.
