ANSWER

EXPLANATION
The given vectors are:

and

To find the dot product of the two vectors, we multiply the corresponding components and add them.

This implies that,


Therefore the dot product of the two vectors is 51.
Considering the withdraws and credits, Lucia's current available balance is of $65.53.
<h3>How do we find a balance?</h3>
It is given by the sum of the money that the people has with the pending credits, and subtracted by the pending withdraws.
In this problem, we have that:
- Lucia has $412.76, with pending credits of $134.00.
- She has pending withdraws of $481.23.
Hence, her avaiable balance is given by:
412.76 + 134 - 481.23 = $65.53.
