Question

This morning, Brenna's father gave her $15 to use in case she wanted to buy a book at her school's book fair. Brenna put the money in her wallet. What integer represents the change in the amount of money in Brenna's wallet? dollars

Answer 1

To determine the change in the amount of money in Brenna's wallet, we need to consider the initial amount of money and any transactions that occur.

Initially, Brenna has $15 in her wallet. If she spends some of that money to buy a book, the change in the amount of money in her wallet will depend on how much she spends.

If she buys a book for a certain amount, let's say \( x \) dollars, then the change in the amount of money in her wallet would be:

\[
\text{Change} = 15 - x
\]

If she does not spend any money, the change in her wallet remains $15.

However, you are asking for the integer representing the change.

If she spends the full $15, the change would be:

\[
15 - 15 = 0
\]

If she does not spend at all, it would be:

\[
15 - 0 = 15
\]

If she spends some other amount, it would yield different integers.

To be more specific, if she spends money, the change will be negative (-x), where x is the amount spent, indicating a decrease in her wallet's total.

But if we take the scenario of her receiving the $15 with no further spending involved, the integer representing the amount added to her wallet is simply:

\[
0
\]

Overall, the integer change in Brenna's amount can be simplified to:

\[
\text{Change in wallet amount} = +15 \text{ (adding money)}
\]
or after spending, might be \( 0 \) or negative based on her transaction.

If you're specifically looking for the immediate change from receiving the money, it is indeed:

\[
\text{Change} = 15
\]
