Answer:
Part A: She borrowed: 3700
Part B: She would pay 555 in interest.
Step-by-step explanation:
Since, simple interest is,
Where, P is the principal amount,
r is the annual rate of interest,
t is time ( in years ),
Part A : Here, S.I. = $ 444,
t = 3 years,
r = 4 %,
Thus,
Hence, She borrowed $ 3700.
Part B :
Here, r = 5 %, t = 3 years, P = $ 3,700,
Hence, She would pay $ 555 interest.
