Answer: the interest rate is 8.3%
Step-by-step explanation:
The formula for determining simple interest is expressed as
I = PRT/100
Where
I represents interest paid on the amount of money deposited.
P represents the principal or amount of money deposited.
R represents interest rate
T represents the duration in years.
From the information given,
P = 800
R = 1000 - 800 = $200
T = 3 years
Therefore,
200 = (800 × R × 3)/100
200 = 24R
R = 200/24
R = 8.3%
