To solve the equation \( x \cdot 50 - 94 = 189 \), we can follow these steps:
- Add 94 to both sides of the equation:
\[ x \cdot 50 = 189 + 94 \]
\[ x \cdot 50 = 283 \]
- Now, divide both sides by 50 to solve for \( x \):
\[ x = \frac{283}{50} \]
- Performing the division:
\[ x = 5.66 \]
Given the options:
- 15,000
- 150
- 1,500
- 150,000
The closest and best estimate for \( x \) is \( 150 \).
