Question

Emma’s mom brought home another 2-pound bag of sugar ( cups) and wants to make fudge to take to work. Her mom will need cups of sugar. a. Write a numerical expression that could be used to determine exactly how much sugar will be left over from the two bags of sugar after Emma bakes cookies and her mom makes fudge. b

Answer 1

The amount of sugar left over after baking is given by the numerical expression 8 cups - (a + b) cups, where 'a' represents the cups used for cookies and 'b' represents the cups used for fudge. We start with 8 cups because there are approximately 4 cups of sugar in a pound, and Emma's mom brought home a 2-pound bag.

Step-by-step explanation:

To determine how much sugar will be left over after making cookies and fudge, you must first know the amount of sugar being used for each recipe.

Let's say Emma uses 'a' cups of sugar for her cookies and her mom uses 'b' cups of sugar for the fudge.

Since Emma's mom brought home a 2-pound bag of sugar, and knowing that there are approximately 4 cups of sugar in one pound, we can calculate the total cups of sugar available as 2 pounds times 4 cups per pound which equals 8 cups of sugar. The numerical expression for the leftover sugar would be:

8 cups - (a + b) cups

Where 'a' is the amount of sugar used for cookies and 'b' is the amount used for fudge.

Simply plug in the values of 'a' and 'b' when they are known to get the amount of leftover sugar.
