To determine how many paperback books Ms. Baldwin will get for free, we start by calculating how many sets of 5 hardcover books she buys.

Since Ms. Baldwin is buying 35 hardcover books, we divide that by 5:

\[
\frac{35}{5} = 7
\]

This means that Ms. Baldwin is buying 7 sets of 5 hardcover books. According to the deal, for each set of 5 hardcover books, she can get 2 paperback books for free.

Now we calculate the total number of free paperback books she will receive:

\[
7 \text{ sets} \times 2 \text{ paperback books per set} = 14 \text{ paperback books}
\]

Therefore, Ms. Baldwin will get **14 paperback books for free**.
