Question 560816: If money is invested for a short period of time, simple interest is paid using the following formula.
I = Prt
P represents the money invested, or principal amount, r is the simple interest rate, and t represents the time, in years, the money is invested.
Given P = $1,000, t = 9 years, and I = $270, what is the simple interest rate?
Answer by jim_thompson5910(35256) (Show Source): You can put this solution on YOUR website!
I = Prt
270 = 1000*r*9
270 = 1000*9r
270 = 9000r
270/9000 = r
0.03 = r
r = 0.03
So the simple interest rate is 3%
