If I could get more context then that would help. Because an exponent being an odd number doesn’t do anything, so it could be either a negative or a positive
Fv=6599.20(1+0.042/12)^12*7
Fv=8850.20
Interest earned=8850.20-6599.20
=2,251
So the answer is a
9: I think it is 48
10: 138
247,039 rounded to the nearest thousand becomes
247,000
