Perform the following calculations for section 6.4, rounding currency to two decimal places where appropriate:

Here are the calculations for section 6.4:

1. $34 \div 4$

   $$\frac{34}{4} = \frac{17}{2} = 8.5$$

   The answer is $\boxed{8.5}$

2. $R 40.60 \div 10.5$

   $$\frac{40.60}{10.5} \approx 3.8666...$$
