Sammie took [tex]\$25[/tex] out of her checking account. After taking the money out, she had [tex]\$100[/tex] remaining. Which equation can be used to find the amount, [tex]c[/tex], Sammie had in her account before she took the money out?

A. [tex]c - 25 = 100[/tex]
B. [tex]c + 25 = 100[/tex]
C. [tex]c \div 25 = 100[/tex]
D. [tex]c \times 25 = 100[/tex]

Answer :

Let's go through this step-by-step to understand which equation can be used to find the amount, [tex]\( c \)[/tex], Sammie had in her account before she took the money out:

1. Sammie initially had an amount [tex]\( c \)[/tex] in her checking account.
2. She took out [tex]$25 from this amount. So, she withdrew $[/tex]25.
3. After taking out [tex]$25, she was left with $[/tex]100.

We want to find the initial amount [tex]\( c \)[/tex], so we can set up an equation to represent this situation:

- When Sammie takes [tex]$25 out of her account, the remaining balance is $[/tex]100.
- Therefore, the equation to show this relationship is:

[tex]\[
c - 25 = 100
\][/tex]

This equation states that her initial amount [tex]\( c \)[/tex], minus the [tex]$25 she withdrew, equals the $[/tex]100 she had left.

So, the correct equation to find the initial amount is:

[tex]\[
c - 25 = 100
\][/tex]
