To solve the problem, let's extract the known conditions and then address each question step by step.

### Known Conditions:
- We need to determine the cost of books based on the information provided in the questions.
- The cost per book is not explicitly given, so we will assume a variable $$ p $$ represents the price of one book.

### Step-by-Step Solutions:

#### 2.1 How much does two books cost?
To find the cost of two books, we can use the formula:
$$
\text{Cost of two books} = 2 \times p
$$

#### 2.2 Describe the relationships that are shown in this graph.
Since the graph is not provided, I cannot describe the relationships shown in it. However, typically, a graph showing the relationship between the number of books and the total cost would be linear, indicating that the total cost increases proportionally with the number of books purchased.

#### 2.3 If Petro buys nine books, how much will she pay per book?
If Petro buys nine books, the total cost can be calculated as:
$$
\text{Total cost for nine books} = 9 \times p
$$
To find the cost per book, we simply use the price $$ p $$ since the cost per book remains constant regardless of the quantity purchased.

#### 2.4 Vasti buys 20 books. How much did she pay in total?
To find the total cost for Vasti who buys 20 books, we can use the formula:
$$
\text{Total cost for 20 books} = 20 \times p
$$

### Summary of Answers:
- **2.1**: The cost of two books is $$ 2p $$.
- **2.2**: The relationships in the graph (not provided) would typically show a linear relationship between the number of books and total cost.
- **2.3**: Petro pays $$ p $$ per book.
- **2.4**: Vasti pays $$ 20p $$ in total.

If you have specific values for $$ p $$ or additional information, please provide them for more precise calculations.
- **2.1**: Two books cost $$ 2p $$. - **2.2**: The graph likely shows a straight line indicating the total cost increases with the number of books. - **2.3**: Petro pays $$ p $$ per book. - **2.4**: Vasti paid $$ 20p $$ in total.
