To determine if Charlotte has enough sugar to make all 12 cupcake recipes, we need to calculate the total amount of sugar required for the recipes and compare it to the amount she has at home.
From the given information, we don't have specific data about the sugar quantities for each recipe. Therefore, we cannot directly calculate the total amount of sugar needed for all 12 recipes.
However, we can determine an estimate or an average amount of sugar used per recipe based on the data presented in the line plot. We'll assume that the sugar quantities on the line plot represent the amounts used in the 12 recipes.
By summing up the sugar quantities on the line plot, we get:
3 + 2 + 4 + 3 + 2 + 3 + 2 + 3 + 3 + 4 + 2 + 3 = 34 cups
The total amount of sugar required for these 12 recipes is 34 cups.
Since Charlotte has 7 cups of sugar at home, we can compare this amount to the total amount needed. If 34 cups is greater than 7 cups, she does not have enough sugar to make all 12 recipes.
In this case, 34 > 7, so Charlotte does not have enough sugar to make all 12 recipes.
To determine how many more cups of sugar she needs to buy, we subtract the amount she has from the total amount required:
34 - 7 = 27 cups
Therefore, Charlotte would need to buy 27 more cups of sugar to have enough for all 12 recipes.
