Answer:
$\$8.855$

Explanation:

The former cost of the book is
$\$8.05$

The new cost of the book is the old cost plus the
$10\%$ of
$\$8.05$ :

$\$8.05+\$8.05(10\%)$

Since:

$10\%=(10)/(100)=0.1$

We have the following:

$\$8.05+\$8.05(0.1)=\$8.05+\$0.805$

Then, the new price of the book is:

$\$8.855$
