1 answer

To find the total amount Miles spent on the three books, we need to add the prices together:

\[ 13.89 + 6.70 + 3.05 \]

Let's do the addition step-by-step:

  1. First, add $13.89 and $6.70:

\[ 13.89 + 6.70 = 20.59 \]

  1. Next, add the result to $3.05:

\[ 20.59 + 3.05 = 23.64 \]

Thus, the total amount Miles spent on the books is $23.64.

So the correct answer is:

$23.64
