Answer:
t = 25 years
Explanations:
The amount borrowed is the principal
Principal = $155,000
Rate = 4.5%
The time = A quarter of a century
A century = 100 years
Quarter of a century = 1/4 x 1000
Quarter of a century = 25 years
The time = 25 years
Since the question is that we should identify the value of time (t)
t = 25 years
