Answer:
3.
Compound Interest,
Calculate: Rate (R)
Where: r = n[(A/P)1/nt - 1]
Total P+I (A): $ 20,000.00
Principal (P): $ 16,000.00
Compound (n): Compounding Annually (1/Yr)
Time (t in years): 2
Answer:
R = 11.803% per year
Simple Interest,
SI = PRT/100
SI = A - P = 20000 - 16000 = 4000
So,
4000 = 16000*R*2/100
1/4 = R*2/100
R = 50/4 = 12.25 % per year
4.
To Calculate: Time (t)
Where: t = log(A/P) / n[log(1 + r/n)]
Total P+I (A): $ 2.00
Principal (P): $ 1.00
Rate (R): % 10
Compound (n): Compounding Annually (1/Yr)
Answer:
t = 7.273 years
Simple Interest,
SI = PRT/100
SI = A - P = 2-1 = 1
So,
2 = 10*t/100
20 = t year
T = 200
