Kate Turabian’s A Manual for Writers of Research Papers, Theses and Dissertations, 7th Edition

In Kate Turabian’s A Manual for Writers of Research Papers, Theses and Dissertations, 7th Edition, she uses the following examples for dollar ranges:

$5-10,000 (meaning five thousand to ten thousand dollars)

$10-15,000? (meaning ten thousand to fifteen thousand dollars)
The dollar sign is omitted before the 2nd figure, and the three zeros are omitted in the first dollar figure.

Wouldn't the reader construe the first figures ($5 and $10), even if only momentarily, as five and ten dollars? Perhaps this is the reason for omitting the second dollar sign before the second figure in each, yes?

Or is this correctly written in your opinion?

Thanks.
