Answer: $63,000
Laura borrowed $105,000
Let the principal be the money borrwed
rate = 5%
Time = 12 years
I = P x R x T / 100
Where I = interest, P = principal, r = rate, t = time
P= $105,000
r = 5%
t = 12 years
I = 105, 000 x 5 x 12 / 100
I = 105000 x 60/ 100
I = 1050 x 60
I = $63,000
The interest she will be paying is $63,000
