After shopping, Danna only has 10% of her money left. She spends $45. How much money does she have left? 

Danna has 10% of her money left after shopping and then spends $45. Let's calculate how much money she had before spending that $45.

Let $ x $ represent the total amount of money she had before spending $45. Since 10% of her money is left, we know:
\[
0.1 \times x = 45
\]

To solve for $ x $, divide both sides by 0.1:
\[
x = \frac{45}{0.1} = 450
\]

Danna had $450 left before she spent the $45. After spending $45, the amount of money she has left is:
\[
450 - 45 = 405
\]

Thus, Danna has **$405** left after her final purchase.
