Answer:
5.73 years
Explanation:
Considering she saved 4.25% in each year of the amount $15000.
So, we have to calculate in what time her saving reaches $1275, if she save each year.
it becomes question of simple interest in which
SI = $1275, Principal P= $5000, time T, rate R = 4.25%
we know SI = PRT/100
1275 = 5000×4.25×T/100
⇒T = 1275×100/(5000×4.25)
⇒ T= 5.73 years
