Final answer:
The new balance in Sarah's account after 3 days, taking into account only the fees and ignoring her initial negative balance, would be -$13.00. However, if her initial negative balance is considered, it would be -$13.75.
Step-by-step explanation:
The subject of this question is mathematics, at the high school level. Specifically, the question deals with calculating the new balance on a checking account after multiple days of being charged a daily fee for a negative balance.
Sarah's current balance is negative $1.25. For every day the balance is below zero, the bank charges her a fee of $4.25. The number of days in question is three. To find the new balance, we will multiply the daily fee by the number of days and then add this total to the initial balance.
The calculation will look like this:
4.25 × 3 = 12.75
-1.25 + (-12.75) = -$13.75
However, the actual options provided in the question seem to exclude the initial negative balance. If we indeed ignore the initial balance, Sarah would simply accrue fees as follows:
4.25 × 3 days = $12.75 in fees
So the correct answer from the provided choices that reflect just the fees accrued over three days would be b. -$13.00, assuming the mistake in arithmetic in the question options presented to the student is overlooked.
