Answer
The two equivalent expressions are:
- \( 7 + 12 \)
- \( 12 + 7 \)
Solution
To find the total amount Brandi earned, we can use the Commutative Property of addition, which states that the order in which numbers are added does not change the sum.
1. The first expression can be written as:
\[
7 + 12
\]
2. The second expression, using the Commutative Property, can be written as:
\[
12 + 7
\]
Both expressions represent the total amount Brandi earned from babysitting and cleaning out the garage, which is \( 19 \) dollars.
Thus, the two equivalent expressions are:
- \( 7 + 12 \)
- \( 12 + 7 \)

Brandi earned a total of \( \$ 7 \) from babysitting and \( \$ 12 \) from cleaning out the garage, which can be expressed as \( 7 + 12 \) or \( 12 + 7 \). Both expressions equal \( 19 \) and demonstrate how you can rearrange the order of addition without changing the sum. Understanding how different ways to add can simplify budgeting is super useful! For example, armed with this knowledge, she could easily track her earnings from various side gigs by applying this property, helping her to keep her finances in check while still having fun with her babysitting and organizing skills.
