Let's analyze the problem step-by-step.
Problem Restatement
Anne starts with some amount of money in her bank account on Friday morning. During the day:
- She writes a check for $240 (which means $240 is deducted).
- She makes an ATM withdrawal of $80 (another deduction of $80).
- She deposits a check of $2 (adds $2 to her account).
At the end of the day, her balance is $1.
What is being asked?
How much money did Anne have in her bank account at the beginning of the day?
Solution
Let:
- xxx = the amount of money Anne had at the beginning of the day.
After the transactions, her balance is:
x−240−80+2=1x-240-80+2=1x−240−80+2=1
Simplify the left side:
x−320+2=1x-320+2=1x−320+2=1
x−318=1x-318=1x−318=1
Add 318 to both sides:
x=1+318=319x=1+318=319x=1+318=319
Final Answer
Anne had $319 in her bank account at the beginning of the day.
