To solve for \( z \) in the equation:
\[ \frac{z}{50} - 95 = 189 \]
First, add 95 to both sides:
\[ \frac{z}{50} = 189 + 95 \]
Calculate the right side:
\[ 189 + 95 = 284 \]
Now, the equation is:
\[ \frac{z}{50} = 284 \]
Next, multiply both sides by 50 to solve for \( z \):
\[ z = 284 \times 50 \]
Calculating \( 284 \times 50 \):
\[ 284 \times 50 = 14200 \]
Now, the question asks for the best estimate for \( x \), but you provided the following options:
- 1,500
- 15,00 (this seems to be a typo, possibly meant to be 15,000)
- 150,000
- 150
The calculated value \( z = 14200 \) fits closest to the option 15,000 if we consider rounding or estimation.
So, the best estimate for \( x \) is:
15,000
