Suppose you begin reading a book on page h and end on page k. if you read each page completely and the pages are numbered and read consecutively, then how many pages have you read?

Options

A. `h + k`
B. `h - k`
C. `k - h + 2`
D. `k -h + 1`

Answer

To determine how many pages you have read from page \( h \) to page \( k \), you can follow these steps:

### Step-by-Step Solution:

1. **Identify the Starting and Ending Pages**:
- Let \( h \) be the starting page.
- Let \( k \) be the ending page.

2. **Calculate the Total Pages Read**:
- The total number of pages read can be calculated by the formula:
\[ \text{Total Pages} = k - h + 1 \]
- This formula accounts for both the starting page \( h \) and the ending page \( k \).

3. **Example Calculation**:
- Suppose \( h = 3 \) and \( k = 6 \).
- Substitute these values into the formula:
\[ \text{Total Pages} = 6 - 3 + 1 \]
- Simplifying this:
\[ \text{Total Pages} = 3 + 1 = 4 \]
- Therefore, you have read a total of 4 pages.

### Final Answer:
The total number of pages read from page \( h \) to page \( k \) is given by:
\[ \text{Total Pages} = k - h + 1 \]
