To find the cost of the hardcover version of the book, let’s denote the cost of the hardcover version as \(\( h \)\).

According to the problem, the cost of the paperback version is \($17.10, and this is $\)2.89 less than the cost of the hardcover version. We can express this relationship with the following equation:

\(\[ 17.10 = h - 2.89 \]\)

Here is the step-by-step process to solve for \(\( h \)\):

1. Write the equation:
\(\[ 17.10 = h - 2.89 \]\)

2. Isolate \(\( h \)\) by adding 2.89 to both sides of the equation:
\(\[ 17.10 + 2.89 = h \]\)

3. Perform the addition to find the value of \(\( h \)\):
\(\[ 19.99 = h \]\)

Therefore, the cost of the hardcover version of the book is:

\(\[ h = 19.99 \]\)

Thus, the hardcover version of the book costs $19.99.
