Question

Carlos deposited $$ \$ 28.50 $$ into his bank account after making a $$ \$ 20.00 $$ withdrawal to pay for some school supplies. Represent these situations as signed numbers (integers). $$ \begin{array}{l}28.50 	ext { and } 20.00 \ -28.50 	ext { and }-20.00 \ 28.50 	ext { and }-20.00 \ -28.50 	ext { and } 20.00\end{array} $$

To represent the situations involving Carlos's bank account as signed numbers (integers), we need to consider the actions he took:

1. **Deposit of $$ \$ 28.50 $$**: This is an increase in his account balance, so we represent it as a positive number: $$ +28.50 $$.

2. **Withdrawal of $$ \$ 20.00 $$**: This is a decrease in his account balance, so we represent it as a negative number: $$ -20.00 $$.

Now, we can summarize the signed numbers for these transactions:

- The deposit is represented as $$ +28.50 $$.
- The withdrawal is represented as $$ -20.00 $$.

Thus, the correct representation of these situations as signed numbers is:

$$
28.50 \text{ and } -20.00
$$

So, the answer is:

**$$ 28.50 \text{ and } -20.00 $$**.
$$ 28.50 $$ and $$ -20.00 $$
