To determine the cost of 10 boolis given that 8 boolis cost \$19.60, we can set up a proportion based on the cost per booli.

1. **Find the cost per booli:**
   $$
   \text{Cost per booli} = \frac{\$19.60}{8} = \$2.45 \text{ per booli}
   $$

2. **Calculate the cost for 10 boolis:**
   $$
   \text{Cost for 10 boolis} = 10 \times \$2.45 = \$24.50
   $$

Now, let's examine the provided options to see which one correctly represents this proportion:

- **(A) $$ \frac{x}{10} = \frac{8}{\$19.60} $$**
  - Solving this gives $$ x = \frac{10 \times 8}{19.60} \approx \$4.08 $$, which is incorrect.

- **(B) $$ \frac{10}{\$19.60} = \frac{x}{8} $$**
  - Solving this also gives $$ x \approx \$4.08 $$, which is incorrect.

- **(C) $$ \frac{8}{10} = \frac{x}{\$19.60} $$**
  - Solving this gives $$ x = \frac{8 \times 19.60}{10} = \$15.68 $$, which is incorrect.

- **(D) $$ \frac{10}{8} = \frac{\$19.60}{x} $$**
  - Solving this gives $$ x = \frac{19.60 \times 8}{10} = \$15.68 $$, which is also incorrect.

None of the provided equations correctly represent the proportion needed to determine the cost of 10 boolis as \$24.50.

**Answer:**
**(I) None of the above**
