Explanation:

Step1: Convert time to hours

30 minutes = $\frac{30}{60} = \frac{1}{2}$ hour

Step2: Set up unit rate formula

Unit rate = $\frac{\text{Total cupcakes}}{\text{Total hours}}$

Step3: Substitute values and calculate

Unit rate = $\frac{12\frac{1}{2}}{\frac{1}{2}} = \frac{\frac{25}{2}}{\frac{1}{2}} = 25$

Answer:

25
