To determine how many months it will take Eva to save for a $1,300 vacation, you can use the following steps:
- Initial deposit: $500
- Monthly savings: $100
- Total amount needed: $1,300
First, calculate how much more she needs to save after her initial deposit:
\[ 1,300 - 500 = 800 \]
Now, we need to figure out how many months it will take to save that additional $800, given that she saves $100 each month:
\[ \text{Months required} = \frac{\text{Amount needed}}{\text{Monthly savings}} = \frac{800}{100} = 8 \]
Thus, it will take Eva 8 months to save enough for the vacation.
The correct response is 8 months.
