First, we determine the total number of cookies in 3 packs. Since each pack contains 10 cookies, we can calculate the total number of cookies as follows:

\[
3 \text{ packs} \times 10 \text{ cookies per pack} = 30 \text{ cookies}
\]

Next, we find the total cost of 3 packs, which is given as $5.10.

To find the cost of a single cookie, we divide the total cost by the total number of cookies:

\[
\text{Cost per cookie} = \frac{\text{Total cost}}{\text{Total number of cookies}} = \frac{5.10}{30}
\]

Now, we perform the division:

\[
\frac{5.10}{30} = 0.17
\]

Thus, the cost of a single cookie is:

\[
\boxed{0.17} \text{ dollars}
\]
