To solve the equation \( 102.5(x - 11.92) = 71.6 \), we can follow these steps:
-
Isolate the term with \( x \): \[ x - 11.92 = \frac{71.6}{102.5} \]
-
Calculate the right side: \[ \frac{71.6}{102.5} \approx 0.6985 \]
-
Add \( 11.92 \) to both sides to solve for \( x \): \[ x = 0.6985 + 11.92 \] \[ x \approx 12.6185 \]
-
Round to three decimal places: \[ x \approx 12.619 \]
Thus, the correct answer is B. 12.619.
