40 $
Step-by-step explanation:
1). 4000 + 960 = 4960 dollars - this is the answer for the first question
2). 960 / 4000 = 0.24 - this means the intrest rate was 24 %
3). 24 % + 1 % = 25 %
4) 0.25 * 4000 = 1000 - this is would be the intrest rate at 25 %
5) 1000 -960 = 40 dollars - she would have earned 40 more dollars with a
25 % interest.
