Answer 1

Let's solve each question step by step.

### Question 1
The original price of the nachos is $13.50, and after adding the tip, the total price is $16.20. To find the percent of the tip:

1. **Calculate the amount of the tip:**
\[
\text{Tip} = \text{Total Price} - \text{Original Price} = 16.20 - 13.50 = 2.70
\]

2. **Calculate the tip percentage:**
\[
\text{Tip Percentage} = \left(\frac{\text{Tip}}{\text{Original Price}}\right) \times 100 = \left(\frac{2.70}{13.50}\right) \times 100
\]

\[
\text{Tip Percentage} = \left(\frac{2.70}{13.50}\right) \times 100 = 20\%
\]

So, the answer to Question 1 is **C** (20%).

### Question 2
The price for a slice of apple pie is $3.25, and we need to calculate the amount after adding 8% tax.

1. **Calculate the amount of tax:**
\[
\text{Tax} = \text{Price} \times \text{Tax Rate} = 3.25 \times 0.08 = 0.26
\]

2. **Calculate the total price after tax:**
\[
\text{Total Price} = \text{Price} + \text{Tax} = 3.25 + 0.26 = 3.51
\]

So, the answer to Question 2 is **C** ($3.51).

### Summary of Answers
- **Question 1:** C (20%)
- **Question 2:** C ($3.51)
