Let's break down the clerk's earnings based on the different rates:

1. Regular earnings:
   The clerk works 40 hours per week at a rate of $45.25 per hour. $\text{Regular earnings} = 40 \times 45.25 = 1810$

2. Overtime earnings:
   Overtime is paid at 1.5 times the regular rate. The clerk works 5 hours of overtime. $\text{Overtime rate} = 45.25 \times 1.5 = 67.875$ $\text{Overtime earnings} = 5 \times 67.875 = 339.375$

3. Holiday earnings:
   Holiday hours are paid at double the regular rate. The clerk works 2 hours on a holiday. $\text{Holiday rate} = 45.25 \times 2 = 90.50$ $\text{Holiday earnings} = 2 \times 90.50 = 181$

4. Total earnings:
   Now, we add up all the components: $\text{Total earnings} = 1810 + 339.375 + 181 = 2330.375$

Thus, the clerk earns $2330.38 for the week.
