Final answer:
To find out the total flour needed, we add the amount for each recipe represented by the Xs on the line plot. After adding all the quantities together, we obtain the total amount of flour needed for all the recipes combined.
Step-by-step explanation:
The question asks us to determine the total amount of flour needed to complete all the given recipes, as shown by a line plot. On the plot, each X represents one recipe and the amount of flour each recipe requires. To find the total, we need to sum the quantities of flour for all ten recipes.
To illustrate the calculation with an example: if a pancake recipe requires 2 cups of pancake mix, 1 egg, and 1/2 cup of milk for one batch, and we want to make 5 batches, then we would need 2 cups times 5 (2 x 5 = 10 cups) of pancake mix, and the milk and eggs would need to increase proportionally. However, this is just an example to help understand the concept of summation.
Based on the line plot data given in the question, the answer is calculated by adding up the amounts of flour for each recipe as represented by each X on the plot. After summing all the values represented by the X's, we get the total amount of flour needed.
