Options

A. 2000
B. 150
C. 200
D. 20000

Answer

To solve the equation \( 50017 = 17 \text{ ones} + 48 \text{ thousand} + \_\_\_\_ \text{ tens} \), we need to find the value that fills in the blank space.

### Step-by-Step Solution:

1. **Understand the Components**:
- The number \( 50017 \) can be broken down into its place values:
- \( 50,000 \) (which is \( 48,000 + 2,000 \))
- \( 0 \) hundreds
- \( 1 \) ten
- \( 7 \) ones

2. **Rewrite the Equation**:
- We can rewrite the equation as:
\[ 50017 = 17 \cdot 1 + 48,000 + x \cdot 10 \]
- Here, \( x \) represents the number of tens we need to find.

3. **Calculate the Contribution of Ones and Thousands**:
- Calculate the contribution of \( 17 \) ones:
\[ 17 \cdot 1 = 17 \]
- The contribution of \( 48 \) thousand is:
\[ 48,000 \]

4. **Combine the Known Values**:
- Now, we can combine these values:
\[ 50017 = 17 + 48,000 + x \cdot 10 \]
- This simplifies to:
\[ 50017 = 48,017 + x \cdot 10 \]

5. **Isolate the Tens**:
- To find \( x \), we can isolate it by subtracting \( 48,017 \) from both sides:
\[ 50017 - 48017 = x \cdot 10 \]
- This simplifies to:
\[ 2000 = x \cdot 10 \]

6. **Solve for \( x \)**:
- Now, divide both sides by \( 10 \):
\[ x = \frac{2000}{10} = 200 \]

Thus, the number in the blank space is **200**.
