Answer:
The savings interest rate of Nakato Nobuki is 3 %
Explanation:
Given;
Final amount of Nakato Nobuki, A = $ 24,000.00
time period of his investment, t = 5 years
principla amount, P = $ 1,500.00
The savings interest rate of Nakato Nobuki can be calculated on a simple interest basis.
A = P(1 + rt)
r is the savings interest rate
Substitute the given values and solve for r
24,000 = 1,500(1 + 5r)
24,000 = 1,500 + 7,500r
7,500r = 24,000 - 1,500
7,500r = 22,500
r = 22,500/7,500
r = 3 %
Therefore, the savings interest rate of Nakato Nobuki is 3 %
