Answer: Charles had 25 dollars in his account last week.
Explanation:
To find out how much Charles had in his account last week, we can use the information given: he withdrew 2 dollars, which was 8% of the balance.
Let's set up an equation to represent this situation:
2 = 0.08 * B
In this equation, B represents the balance in Charles' account last week.
To solve for B, we can divide both sides of the equation by 0.08:
2 / 0.08 = B
This simplifies to:
25 = B
Therefore, Charles had 25 dollars in his account last week.
So, the answer is that Charles had 25 dollars in his account last week.
