Answer :
Answer: 2285.71
Step-by-step explanation:
Rearranging the simple interest formula, we have P = A / (1 + rt), where P is the Principal, r is the annaul rate and t is the time period.
r = R/100 = 5%/100 = 0.05 per year.
Solving the equation:
P = 3200 / ( 1 + (0.05 × 8)) = 2285.7142857143
Answer:
Grandma deposited 8,000
Step-by-step explanation:
I = 3200
r = 5 %
t = 8 years
[tex]P =\dfrac{I*100}{r*t}\\\\P = \dfrac{3200*100}{8*5}\\\\P= 8000[/tex]
