Answer :
To solve this problem, let's think about what happens when Sammie takes money out of her checking account.
1. Setup the Problem:
- Let [tex]\( c \)[/tex] represent the initial amount of money Sammie had in her checking account before withdrawing any money.
- Sammie took out \[tex]$25 from her account.
- After the withdrawal, the remaining balance in her account is \$[/tex]100.
2. Translate into a Mathematical Equation:
- The action of withdrawing \$25 from the account means that [tex]\( c \)[/tex] was reduced by 25 to result in a balance of 100.
- This situation can be written as the equation:
[tex]\[
c - 25 = 100
\][/tex]
3. Verify Understandability:
- This equation makes sense because:
- [tex]\( c \)[/tex] is the original amount,
- Subtracting 25 represents the money taken out,
- The remaining [tex]\( 100 \)[/tex] is what was left after the withdrawal.
Thus, the correct equation that represents the situation is [tex]\( c - 25 = 100 \)[/tex]. This equation can be used to find out how much money Sammie initially had in her account.
