Answer 1

To find out how long it will take Brooklyn to save a total of $100, we first need to determine how much more money she needs to save beyond her current balance of $35.25.

1. Calculate the amount she still needs:
\[
100 - 35.25 = 64.75
\]

2. Next, determine how many weeks it will take her to save the remaining $64.75 at the rate of $4.25 per week:
\[
\text{Number of weeks} = \frac{64.75}{4.25}
\]

3. Perform the division:
\[
\frac{64.75}{4.25} \approx 15.24
\]

4. Round to the nearest whole number:
\[
15.24 \text{ rounds to } 15
\]

Therefore, it will take Brooklyn approximately **15 weeks** to save a total of $100.

The answer is **15**.
