To find out how much vanilla extract Veena needs for 4.7 batches of muffins, you can multiply the amount of vanilla extract required for one batch by the number of batches.
Veena's recipe calls for 2.25 mL of vanilla extract per batch.
So, for 4.7 batches:
\[ \text{Vanilla extract needed} = 2.25 , \text{mL} \times 4.7 \]
Calculating that:
\[ 2.25 , \text{mL} \times 4.7 = 10.575 , \text{mL} \]
Thus, Veena needs 10.575 mL of vanilla extract to make 4.7 batches of muffins.
The correct response is 10.575 mL.
