Final answer:
After subtracting the quarter cup of Bisquick Ms. Murray has already added (0.25 cups) from the total required (2.45 cups), she will need to add 2.20 more cups of Bisquick to the mixture.
Step-by-step explanation:
Ms. Murray needs 2.45 cups of Bisquick to make her pancakes. Since she has already added 1/4 cup of Bisquick, we must subtract this amount from the total she needs to find out how much more Bisquick is required.
To calculate the remaining amount needed, use the following steps:
- Convert 1/4 cup to its decimal form, which is 0.25 cups.
- Subtract 0.25 cups from the total amount of Bisquick needed, 2.45 cups.
- The calculation will be 2.45 cups - 0.25 cups = 2.20 cups.
Therefore, Ms. Murray needs to add 2.20 more cups of Bisquick to her mixture.
