Let's solve the expression step by step:

$23.5 \left(1 + \frac{7.048}{5.231}\right)$

1. First, divide $7.048$ by $5.231$:

$\frac{7.048}{5.231} \approx 1.347$

2. Add 1 to the result:

$1 + 1.347 = 2.347$

3. Now multiply this by $23.5$:

$23.5 \times 2.347 \approx 55.1545$

So, the result is approximately 55.15.
