To calculate your earnings for a 40-hour work week, we first need to determine your hourly rate. Here's how:

1. Calculate the hourly rate:

$\text{Hourly rate} = \frac{681.60}{32} = 21.30 \, \text{per hour}$

2. Multiply the hourly rate by 40 hours:

$\text{Earnings for 40 hours} = 21.30 \times 40 = 852.00$

So, you would earn $852.00 for a 40-hour work week.
